RE: [nfc-l] Epic Movement - Etna, NY

2020-10-04 Thread John Kearney
Hi Bryan, 

Thanks very much for continuing this discussion. I very much appreciate the 
opportunity to share some thoughts with a meteorologist. 

Unfortunately, yes, Windy.com has no archives. I am studying coastal migration 
patterns using acoustic monitoring. Generally, I have not completed data 
processing until well after migration events.

I think upper-air data from nearby stations, such as Yarmouth, may be an 
alternative approach to viewing wind speed and direction at different 
altitudes, but it lacks the composite perspective.

John

John (and others),

For the easternmost third of North America, 850hPa can be too high, that's 
true.  Looking at a level like 950 or 925hPa would be really useful for you in 
Nova Scotia (or any coastal location).  Yet this isn't available on 
earth.nullschool.net <http://earth.nullschool.net> . If you wanted to see the 
different levels of winds between 1000hPa and 850hPa, you could go to windy.com 
<https://www.windy.com/-Cloud-base-cbase?950h,cbase,44.719,-63.812,6> .  Here 
you can adjust vertical levels with a little more granularity AND you can also 
turn on cloud bases which would be helpful for NFC predictions (lower cloud 
bases = better probability of hearing calls).  You cannot, however, go 
backwards in time (as far as I know) to see previous dates that were of 
interest to you.

 

Overall, the forecasted winds from computer models can be useful for prediction 
of migration changes as well as when concentrations of birds will be higher in 
a given area or not.  What Chris had the other day 
<https://earth.nullschool.net/#2020/09/18/0300Z/wind/isobaric/850hPa/orthographic=-77.30,42.81,960/loc=-76.383,42.485>
  was a great example of the winds coming from an appropriate origin, a large 
scale convergence pattern for his area, and likely lower cloud bases with the 
passage of the weak cold front. The speed of the front helped as well, making 
the event last longer over his area as birds were likely piled up at the 
frontal boundary itself since the wind shift on the opposite side of the front 
was not conducive for migrants.  

 

Thanks,

Bryan

Lee and others,

I didn't see this at the time because it unfortunately went to spam.  

 

The website earth.nullschool.net <http://earth.nullschool.net>  is available 
for anyone to use and gives computer modeled streamlines that can help with 
predicting migration patterns.  It is best to look at the 850hPa (mb) level 
when looking for migrational movements away from taller topography.  There is a 
lot more to it than that, but Chris's example was a really good one to use.  On 
that website, you have the ability to go back in time to Dec 31 of 2013, so 
feel free to time travel to look at your "best days" and see what the weather 
was like.  Also, you can move forward  in time approximately 4 days.  All of 
the controls for this site are in the "Earth" button in the bottom left corner. 
 

 

Caveat: This website uses computer model data and computer models can be quite 
wrong, especially the further forward in time you travel.  So take the forecast 
maps with a large grain of salt.  The maps from the past are also from this 
same computer model, so there are still errors, but they are smaller errors 
than the forecasts have in them.  

 

Sorry for the delayed response.

Christopher,

Based on your signature location and the current wind pattern: 

https://earth.nullschool.net/#2020/09/18/0300Z/wind/isobaric/850hPa/orthographic=-77.30,42.81,960/loc=-76.383,42.485

 

You should be seeing this likely through the night with numbers getting less as 
the night goes on but plenty of migrants. I have an article coming out in the 
Fall North American Birds about why this is the case. 

 

For the short and sweet, looking at the right altitude for migration, the winds 
are the right direction for fall migrants into your area, the origin is quite 
distant from you, and there is a frontal passage at right this time getting you 
some extra convergence of birds in your area. The larger scale pattern shows 
that there may be better places than where you are in terms of large scale 
convergence, but your pattern is pretty damn good for migrants. 

 

If you have questions, ask. I am happy to talk more about this.

Posted the following to the NFC Facebook group just now and thought I would 
share here:





 








I’ve been listening live in Etna, NY tonight since 10:30pm. This has been an 
epic migration night here and one of the more constantly vocal in recent 
memory. Literally thousands and thousands of calls. Nearly constant calls of

warblers, thrushes, (and tanagers?), grosbeaks, occasional sparrows, all 
stepping upon one another. First regular groups of Gray-cheeked Thrushes late 
tonight. One Black-billed Cuckoo.

Only just now was there a notable gap of some 10-20 seconds without a call, as 
a group of coyotes started yipping and whooping. 



















Most impressive night to be listening prior to this first calm. It will be 
interesting to try to run these data through Vesper (I am recording to file 
sequence using Raven Pro; plus recording the full night with my Swift recorder

and Flowrabola microphone.) 



















Good night-listening!

 





 

Sincerely,

 

Chris Tessaglia-Hymes

Hi Debbie and all,

I have had unusually high numbers of Canada Warbler NFCs last autumn (2017) and 
this autumn (2018). I’ve had more Canada Warblers in 2018 but I’m using a more 
powerful microphone (OldBird 21c) this year compared to a Wildlife Acoustic NFC 
microphone in 2017.

 

Beaver River, Yarmouth County, Nova Scotia, Autumn 2018: 516 NFCs for an 
estimated 387 birds

Cape Forchu, Yarmouth County, Nova Scotia, Autumn 2017: 287 NFCs for an 
estimated 226 birds.

 

The peak occurs in the month of August.

Hey Everyone,

Here in western Montana, we've recorded more Canada Warbler NFCs this fall than 
in past years. We had more microphones too, but it seems maybe something else 
is going on. Did any of you Easterners see higher than usual numbers of NFCs or 
know if they had an above average breeding season? Forest fire smoke was also 
pretty bad up there so we've wondered about the influence of that, too.

RE: [nfc-l] I think it is sora

Hi All,

If in doubt about a Sora call, I would encourage people to view the 
spectrograms for Sora in the Macauley Library. Spectrograms that show a sharply 
rising slope through most of the call are quite possibly Spring Peepers. Sora 
calls are longer and have a fairly long, relatively flat or gently rising slope 
in the first part of the call.

I use Kaleidoscope for the analysis of my recordings. I have 6 SONY tape

Hi Dioni,

I use Raven from the Cornell Lab of Ornithology for my acoustic work. Like 
Kaleidoscope it has a free version, Raven Lite, but you really need to have 
Raven Pro if you want to use a detector.

There is a Facebook page “Nocturnal Flight Calls” where you can also post 
unidentified or mysterious flight calls! Don’t hesitate to send me a friend 
request.

William Evans and Michael O’Brien are both members of this list, I believe, so 
they might be able to update us about when the next printing of their guide 
will be available.

I reviewed the call you posted last night. To me, the possibilities are Swamp 
Sparrow, Lincoln’s Sparrow, or Indigo Bunting.

Hello John,

 

Thank you very much for your answer.

 

Kaleidoscope is really an interesting program. I prefer it to audacity 
especially because we can cut a selected segment and also because it treats 
records of more than 6 hours on short segments, so easier to work (because the 
computer is less slowed).

 

Indeed, many of my calls are not very clear. I start the study with sonogram, I 
am not yet very familiar with the programs. I get used to it slowly! Thank you 
so much for your help identifying my sonograms. I had a good idea of ​​the 
graphics except for Chipping sparrow and Common Yellowthroath. If you have 
Facebook, I would love to have you in my list of friends, because I will add 
continuously, without doubt, other graphics sp. which I remain in uncertainty.

 

Thank you very much for offering me documentation. In the case of the Evans 
CD-ROM, it no longer seems accessible. Apparently, when I go on the internet, a 
new edition should arrive in 2017, is this the case?

Hi Dioni,

Thanks for sharing some of your night flight call clips. I’ve never used 
Kaleidocsope so it interesting to see what a spectrogram looks like on the 
program. Some of your calls were not very clear, perhaps because they were 
distant. In any case, you might try adjusting your spectrogram parameters and 
time/frequency axes to see if it brings more clarity. Among the ones I could 
discern, a number appeared to be White-throated Sparrows. I also saw Chipping 
Sparrow, Hermit Thrush, Swainson’s Thrush, Common Yellowthroat, and American 
Robin.

 

The best guide to night flight calls is the CD-ROM by Evans and O’Brien, Flight 
Calls of Migratory Birds. I believe it is currently out of print but there’s a 
good chance that it is available in a library. Otherwise, I would recommend the 
website of Paul Driver, http://pjdeye.blogspot.ca/, and scroll down his right 
menu for the flight calls of various species groups.

 

Hope this helps and best of luck in your listening!

[nfc-l] Early migration

2017-08-02 Thread John Kearney
Hi All,

I've been running my microphone since July 28th. Last night (August 1st) had
the highest total so far. Some of these birds may be in post-fledgling
movements within the province of Nova Scotia. Some are very likely
migrating, e.g., Yellow Warbler, American Redstart, Black-and-White Warbler,
and Canada Warbler. The closest weather radar at Caribou, Maine indicates
very low density of echoes so far. The totals for last night are listed
below.

Hi Preston,

Lesser Yellowlegs is possible but the other suggestions made so far are good 
too. Perhaps as you originally wondered, they are overlapping calls of two 
birds of a different species.

RE: [nfc-l] 2016 Fall NFC Update

2016-12-05 Thread John Kearney
Dan, Debbie, and All,

Thanks for the reference Dan. It is indeed an exciting paper that breaks new 
ground and raises intriguing questions. In reference to the paper’s conclusion 
about the need for larger-scale studies, I would add that there is a 
corresponding need for smaller-scale studies of aerial habitat, using smaller 
marine-type radar and acoustic monitoring.

 

In response to Debbie’s question, one of my sites is about 20 km inland and in 
a ravine with a river at the bottom and thus at very low elevation relative to 
the surrounding topography. Yet this site has relatively high counts of flight 
calls (in a dark forest environment) in the autumn. I hypothesize that this is 
due to migrants following the river system to the coast. At another site 
located on a coastal headland, I also have high counts in the autumn. Two 
stations that are 1.5 and 3.0 km from the headland have increasingly smaller 
counts with distance from the headland. Here I hypothesize the higher counts 
(and probably lower altitudes) at the headland are due to re-orientation 
behaviour.

Biology Letters about the height of nocturnal migrants: "Where in the air? 
Aerial habitat use of nocturnally migrating birds" by Kyle Horton and 
colleagues.  The article reports a lot of variation in flight height of 
nocturnal migrants.  In relation to inland versus coastal habitat, the authors 
report: "migrants tended to fly slightly higher at inland sites compared with 
coastal sites during spring, but not during autumn."

 

Here is the full abstract.

 

The lower atmosphere (i.e. aerosphere) is critical habitat for migrant birds. 
This habitat is vast and little is known about the spatio-temporal patterns of 
distribution and abundance of migrants in it. Increased human encroachment into 
the aerosphere makes understanding where and when migratory birds use this 
airspace a key to reducing human–wildlife conflicts. We use weather 
surveillance radar to describe large-scale height distributions of nocturnally 
migrating birds and interpret these distributions as aggregate habitat 
selection behaviours of individual birds. As such, we detail wind cues that 
influence selection of flight heights. Using six radars in the eastern USA 
during the spring (2013–2015) and autumn (2013 and 2014), we found migrants 
tended to adjust their heights according to favourable wind profit. We found 
that migrants’ flight altitudes correlated most closely with the altitude of 
maximum wind profit; however, absolute differences in flight heights and height 
of maximum wind profit were large. Migrants tended to fly slightly higher at 
inland sites compared with coastal sites during spring, but not during autumn. 
Migration activity was greater at coastal sites during autumn, but not during 
spring. This characterization of bird migration represents a critical advance 
in our understanding of migrant distributions in flight and a new window into 
habitat selection behaviours.

Hi Debbie,

Very interesting work. Low elevation in your area would be very high in a 
coastal area. It makes me wonder how the preferred flight altitude of a migrant 
is related to sea-level and local geography.

RE: [nfc-l] NFC Report Week of 10/1 through 10/7/2016

Yes we had over 100 mm of rain and over 100 km/hr wind. A strong wind can blow 
water through small holes too. I found that tipping a flower pot mic slightly 
helps to let the water run off.

John,

 

I built my mic using the plans on Bill Evans' site. I waterproofed it by 
putting plastic wrap over the top, however there is an infinitesimal hole where 
the audio cable comes through, and apparently water got in through that. I had 
never had problems before, so I figured it would be fine. I guess the rain was 
just too  heavy that day though.

Hello all,

 

Sorry I've fallen a bit behind in posting these, I've been extremely busy and 
just haven't had time to go through my calls. High school is such a blast. 
Anyway, getting down to the interesting stuff... 

During this period my supposedly waterproof homemade mic managed to get soaking 
wet in a huge rainstorm, so I was unable to record on 3 nights while I waited 
for new parts to arrive. This week I had 265 calls, of which 189 were 
identifiable.The most numerous call was Swainson's Thrush. Below are totals for 
each night, as well as species totals (estimated minimum individuals in 
parentheses)

 

10/1 48 (Moderate E/SE winds)

 

10/2 No data

 

10/3 No data

 

10/4 No data

 

10/5 143 (Moderate NE winds)

[nfc-l] Weekly report

2016-10-09 Thread John Kearney
Hi All,

My weekly report on nocturnal migration in Nova Scotia is available for the
1st week of October at:
http://www.johnfkearney.com/Carleton_YarmouthCounty_2016.html.

 

Nocturnal migration here was only 1/5 of what it was during the previous
period. Some of the later migrants like Orange-crowned Warbler, Black-capped
Chickadee, and Dark-eyed Junco began to appear this week.

The most common birds were Yellow-rumped Warblers and White-throated
Sparrows.

There is a lot happening with night flight calls these days. Another action

RE: [nfc-l] Bicknell's Thrush - More Classic Example

2016-09-26 Thread John Kearney
Hi Chris,

I was hoping someone else would give you some feedback on your nice series of 
thrush calls. Not only have I been talking too much lately but this topic can 
be a special quagmire. 

I want to note that I have one monitoring station that is the first landfall 
directly southwest of the island of Newfoundland. Therefore, the flight calls 
of Gray-cheeked Thrush that I record there are very likely Catharus minimus 
minimus. They are consistently less humped and more descending than Catharus 
minimus aliciae. Their maximum frequency is 4 KHz or a little greater. I had 
another monitoring station that is the first landfall southwest of Cape Breton 
Island where Bicknell’s Thrush breed. These thrush calls have a maximum 
frequency over 5 kHz. I have attached a photo illustrating these three types of 
calls, including one from Louisiana provided by Bill Evans. Perhaps some of 
your calls are C.m.minimus. Given this race is believed to winter in South 
America, including Columbia, one cannot rule out the possibility of them flying 
over Etna, NY. 

It would be interesting to get a series of night flight calls from these two 
species in areas close to their breeding range.

Thanks,

John Kearney

Albeit soft and slightly distant, this bird was recorded over Etna, NY on 23 
September 2016 at 23:25. 

 

I would consider this to be a classic example because its peak frequency is 
above the 5kHz “safety” demarkation line.

 

This bird peaks around 5.25 kHz and has an overall duration of about 250 
milliseconds. Similar to the “possible Bicknell’s Thrush” examples posted 
yesterday, the sharp onset followed by a variably modulated and notably longer 
trailing descent is the call structure which caught my eye while browsing 
through my data last night.

 

Attached are both the recorded call (with some lower cricket and noise bands 
gently filtered out) and a screen grab of the call for visual representation.

 

Good night listening!

 

Sincerely,

Chris T-H

RE: [nfc-l] Interesting Savannah Sparrow Call

2016-09-26 Thread John Kearney
Hi All,

As an update to my response to Preston’s post yesterday, Jerald sent me offline 
a copy of a blog entry by Paul Driver on Ipswich Sparrow flight calls 
(http://pjdeye.blogspot.ca/2009/12/ipswich-sparrow-flight-calls.html). 
Recordings of the flight calls of Ipswich Sparrows in NJ show that their 
frequency can be much lower than previously thought and that the feature most 
distinguishing them from the nominate race of Savannah Sparrow is the degree of 
modulation in the call. This sheds a new light on Preston’s call in Westport.

It is interesting to note that I posted what I thought might be an Ipswich 
Sparrow flight call to this forum on 18 September 2013. Attached is a photo of 
the spectrogram, and the wav file can be found in the archives for that date. 
The call was recorded at Canso, NS. The point on the mainland of North America 
closest to Sable Island. Based on Paul Driver’s blog post, this call would also 
be a good candidate for Ipswich Sparrow.

Hi Preston,

You indeed have an interesting call. My feeling is that it is a highly 
modulated Savannah Sparrow rather than “Ipswich” Savannah Sparrow. I believe an 
Ipswich Sparrow should be of a higher frequency overall. That being said, I 
think we need some more examples of Ipswich flight calls and come up with a 
range of measurements for analyzing spectrograms.

It is also unlikely, not impossible, but unlikely that you would have an 
Ipswich Sparrow in Connecticut this early. Juvenile Ipswich Sparrows start 
leaving Sable Island in late September and will usually spend time on the coast 
of Nova Scotia and Maine before heading further south. Adults don’t leave until 
October.

You might find this You Tube video interesting about recent radio telemetry 
studies on the timing of migration and movements of Ipswich Sparrows:

While looking through the results of last night's extremely productive 
recording, I stumbled upon a very interesting savannah sparrow call which is 
superficially similar to an Ipswich call, mainly because it is highly 
modulated. As Ipswich savannah sparrows are very rare in Connecticut, I was 
wondering if anyone could confirm or refute this tentative ID. Attached is a 
screenshot of the spectrogram, and (a very brief) clip of the call.

RE: [nfc-l] Interesting Calls

2016-09-24 Thread John Kearney
Hi Jerald,

I think some of the quality of the calls is lost when I convert your mp3s to 
wav files. I had a bit of trouble reading the spectrograms. There were a number 
of birds in those recordings. I could discern Swainson’s Thrush, Hermit Thrush, 
one Rose-breasted Grosbeak, and perhaps one or two Veery.

I have had a few interesting calls this week as well. They sound rather 
thrush-like, but don't match any of the thrushes. I'm guessing they're 
Rose-breasted Grosbeak, but I would appreciate confirmation.

Hi all,

I just wanted to post a reminder that when sending out flight calls for ID, 
some of us would really appreciating your leaving a second or two before and 
after the target sound. This really helps a lot when trying to actually listen 
to the recordings, as it can end up sounding like just a wall of sound 
otherwise, with the target voc impossible to pick out of the noise without some 
introduction first. Boosting the gain (normalizing) the clip would also be 
helpful in many cases. Both of these are also very important for prepping 
recordings for upload to eBird, if that is something anyone on here is 
interested in doing.

 

Thanks!

A night ago I recorded a couple interesting calls, which I have failed to 
identify spectrographically. If anyone could help in their identification, I 
would be very appreciative.

RE: [nfc-l] NFCs Week of 9/3 through 9/9

Hi Laura and all,

My total includes thrushes. The thrushes are listed in the table; 88 Swainson’s 
Thrush and 11 Veery calls for the week.

Folks,

 

I haven't had time to look at my recordings much, so I have no counts to share. 
My home recording station has very prominent insect song, so that I get 
thousands of false hits, making screening time-consuming. However, I do know 
that we had significant thrush movement the night of September 8-9, undoubtedly 
mostly Swainson's. I heard them while outside both evening and morning.

 

John -- are your results higher frequency only, or did you actually have no 
thrushes at all?

Hi Jerald and all, 

I think I fared slightly better than Jerald.  I had a few calls at least each 
day. But no thrushes or thrush-like calls! Here are my totals.

 

2-Sep 81 

3-Sep 197 

4-Sep 213 

5-Sep 153 

6-Sep 150 

7-Sep 106 

8-Sep 19 

9-Sep 5 

10-Sep 48 

11-Sep 16 

A total of 988 calls. 

 

I have not yet dared to classify all the calls but definitely there were lots 
of Ovenbirds, Magnolia, Bay-breasted, Savannah Sparrows, Black-throated green 
types, Chestnut-sideds, a few No. Parulas and a few Black-thorated blues. Very 
rarely American Redstart. 

 

Cheers

RE: [nfc-l] migration technologies overview

Thank you, Jeff. It is indeed a useful summary of the state of the art. 

I recently received some literature on a new version of the Kaleidoscope
bioacoustics software with cluster analysis by Wildlife Acoustics. Has
anyone used this new version for the analysis of night flight calls?

Hi Preston and all,

I downloaded the calls you sent. The first one is a "double-up" warbler
mostly likely one in the genus Oreothlypis (Nashville, Tennessee, and
Orange-crowned). I would lean toward Tennessee for this one due to the nice
bend in the spectrogram. When I first looked at the second call, I thought
it was a Magnolia Warbler due to the spacing between humps, but on closer
examination its high frequency, number of humps, depth between humps, and
somewhat descending character fit better with Cape May Warbler.

Hi All,

Yesterday morning, 13 August, four minutes before civil sunrise at 0551
hours (0852 UTC,) in Carleton, Nova Scotia, I recorded what appears to be a
fall-out of American Redstarts (AMRE) and Black-and-White Warblers (BAWW).
In the space of 1 minute and 20 seconds, there were 21 American Redstart
calls and 39 Black-and-White Warbler calls, plus an Ovenbird (OVEN), and a
few unidentified warblers. A screen-capture of my Raven Pro review panel is
attached and shows the calls for this 1.33-minute period. Please note that
there are a few duplicate clips in the photo for those cases where calls
were overlapping.

I should note that an air quality warning was in effect in the areas just
northeast of my monitoring station due to a number of wildfires. There was a
light shower at the station between 0130 and 0157 hours. Otherwise, there
appeared to be no other unusual atmospheric conditions.

While it is possible that this was a flock of birds already on the ground
and moving with first light, the pattern of calls is similar to what I've
seen before for autumn fall-outs of warblers, usually much later in the
season, in mid-September.

[nfc-l] Nocturnal Migration for the 1st Week of August in Nova Scotia

2016-08-08 Thread John Kearney
Hi All,

The rate of nocturnal movements of warblers almost doubled over the previous
week at Carleton, Yarmouth County, Nova Scotia. There was a total of 240
calls and at least 181 individual birds at a rate of 34 calls per night.
Warblers composed 99% of the calls recorded. Despite a continuing variety in
species composition, early migrating warbler species dominated the count.
The most common species were American Redstart (69 calls), Black-and-White
Warbler (45 calls), and Yellow Warbler (34 calls). The numbers of these
three species seemed to indicate true, south-bound migration, rather than
post-breeding dispersion. A summary list can be found below.

The closest weather radar that provide online base reflectivity and velocity
data while operating in clear air mode are in the state of Maine, at Caribou
and Portland. Both of these radars are located approximately 350 kilometers
from the monitoring station. The radars showed only a light density of
echoes (~60-70/cubic km) during the week. Velocities indicated that there
was some bird migration on each night when there was no rain.

Previous reports and more information can be found at:

RE: [nfc-l] Sparrow/warbler NFCs last night

2016-08-03 Thread John Kearney
Hi Jerald,

Here are some thoughts are your calls.

The first could be a VESP that is shorter duration than average. It could also 
be an OVEN. It seems to have the arch of an OVEN.

The second one is rather indistinct. Possibilities might be YRWA, BTNW.

I had 2 high pitched calls last night, could someone tell me what they are? I'm 
thinking the first one could be VESP, it looks similar to sonograms I've seen 
for that species. I'm really not sure what the second one is.

(see below).

Subject: Alternate NFC Recording Devices (WAS Re: [nfc-l] Migrants 5/24/16)

 

Hello all,

I've been lurking here for a couple years with the intention of eventually
setting up an automated listening station with a RaspberryPi or similar
cheap, low-power ARM device. Unfortunately I currently live in bad area for
noise (< 1 mile away from a major freeway and directly adjacent to a major
arterial road) so I haven't even bothered. Fortunately I'm about to move to
a much better location and looking to hopefully set something up prior to
fall migration. 

 

In the meantime, here are a few things I've learned doing research. 

 

As mentioned, you'll need some sort of way to get analog audio to a USB
input. There are cheap (< $10) usb sound cards out there, but I'm assuming
the inputs would likely be fairly noisy which could make it even more
difficult to detect NFC's in the resulting recordings. A better option would
be something like the Blue Icicle device mentioned. Other devices that look
promising to me are the ART USB Dual Pre and Behringer 302USB. The later two
options give you more options such as EQing, auxiliary outs, headphone outs,
etc. 

 

Raspberry Pi's have been known to corrupt a microSD card if you write a lot
of data (say audio files) to them frequently. I've heard the best option is
to write data to a USB thumb drive. Not sure if newer RasPi's or other
similar devices have this issue. This has the nice bonus of giving you the
ability to swap out drives as needed if your device is not local or easy to
access. 

 

There is an open source audio tool called SoX  ( http://sox.sourceforge.net/
) which is run from the command line and can do everything you'd require
from an NFC recording station. I'm pretty rusty in my Linux scripting, but
I'm sure it'd be fairly easy to write a script that automatically started
recording at X and ended at Y. Heck, it probably wouldn't be terribly
difficult to base X and Y on sunrise/sunset times for that given day. 

 

The real amazing thing would be if you

Raspberry Pi is not optimized for low power consumption, so if you're

board-based computers which are a bit more careful about power. I've heard
good things about Beaglebone.

Thanks for the info, Jesse. I did hear about the sound card for Rasberry Pi. 
There is the Blue Icicle that has an XLR adapter, USB connection, and pre-amp 
that could be used with a computer that has a sound card. I’d like to find a 
small computer than can record for a few days to a week on D-batteries. Perhaps 
no such thing exists as yet. I suspect even Beaglebone would require more power 
than that?

Thanks Jerald. I find it very interesting to learn what other people are using 
for nocturnal monitoring. It often gives me new ideas. I’m curious to know if 
anyone has tried using the Raspberry Pi computer as a recording device and how 
long it could run on batteries.

Hi John, I'm in Delaware, I meant to include that and forgot. Yes, I record 
overnight, and I save calls that I hear live. I'm using a mic that I built 
loosely following the plans on the Oldbird website, and a preamp that I bought 
from Amazon. For recording I use Raven lite while listening live, but I record 
overnight with audacity and the oldbird detectors.

Hi Jerald,

This looks and sounds like a Spotted Sandpiper to me. When I’m searching for 
Spotted Sandpiper in my recordings, I set the detector to 4 – 5 kHz. The 
Solitary Sandpipers that have passed through here in Nova Scotia are 6 kHz or 
more on the upper part of the spectrogram.

could someone please tell me whether this call is a spotted or solitary

Hi All,

To enhance this listserv as a learning medium, I think it is important to try 
to find a consensus on identification questions. After looking at more low 
frequency flight calls (including those on Paul Driver’s blog), I also agree 
that Orchard Oriole is the best choice.

Hi everyone,

 

Lots of recent activity here in western Pennsylvania, including a few calls 
that I wouldn’t mind second opinions on.

 

 

First is the attached call labeled “Unknown1” which sounds to my ear quite like 
the “yeehr” of an Orchard Oriole, but this species (according to the Evans and 
O’Brien CD) is not known to call on nocturnal migration. Is there something 
else this call could be? I will say this isn’t the only time I’ve heard this 
type of call over my yard but this is by far the best recording I’ve gotten of 
a call of this type. (May 2 at 12:31am)

 

Second (Unknown2) is another low-frequency call like the possible Least Bittern 
I posted last week. This one sounds like a Black-crowned Night-Heron to me … 
any other ideas? (May 2 at 1:43am)

 

Lastly is the call I listed as Cedar Waxwing on this eBird checklist:  
 
http://ebird.org/ebird/view/checklist?subID=S29290856. This would be the first 
nocturnal Cedar Waxwing call I’ve had here, and was wondering if this really is 
definitive or if there are any other possibilities for this call. It seems 
pretty spot on for waxwing and apparently they are known to call at night 
occasionally, but I always like to be cautious with “presumed” birds like these.

 

 

 

Of general interest, the biggest night of the year here so far was May 1-2, 
which was interrupted by a thunderstorm that came along around 3:45am. Here is 
the post-midnight checklist with several clips:  
 
http://ebird.org/ebird/view/checklist?subID=S29412937. Both of the attached 
Unknowns were made on this same night, by the way.

 

On May 3 I was surprised to hear a Greater Yellowlegs song on the recordings: 
see   
http://ebird.org/ebird/view/checklist?subID=S29429788. 

 

 

As always if there are any errors in any of these checklists please let me 
know.

Thanks for your summary of your recent paper. I look forward to hearing more

Hello Everyone,

It is nice to find renewed interest in the NFC-L list.

Thank you, Laura, for posting this information about the article my research 
team published in *Condor: Ornithological Applications*, concerning 
ground-level lights and NFCs.  I thought I would provide a brief explanation of 
our research.  My students and I conducted simultaneous NFC recordings at 
adjacent "dark sites" (no artificial lights) and "light sites" (sights with a 
low-level artificial light, such as a porch light or a street light).  We found 
significantly higher numbers of NFCs above the light sites compared to the dark 
sites; on average, we found three times the number of NFCs about the light 
sites (on average, 31 NFCs per night above light sites compared to 11 NFCs per 
night above dark sites).  We also found a greater diversity of species 
producing NFCs about light sites, but this difference was not significant (on 
average, 6.5 species or species-groups above light sites compared to 4.5 
species or species-groups above dark sites).  We conducted these recordings at 
16 pairs of sites in southern Ontario, north of Lake Erie.

The take-away message from this paper: ground-level lights influence the 
behaviour of birds passing overhead in migration, even low-level lights like 
the lights in our backyards.  We don't know if this is because birds are 
lowering their altitude in response to lights, or changing the course of their 
migration to pass over the lights, or being induced to call more often over 
lights compared to dark sites.  I plan to try to study these alternatives, 
going forward.

I'd be happy to share my "author's copy" of our *Condor* paper to anyone who 
wants to read it; please email me off the list.  I'd also like to point out 
that my website has a set of spectrograms of NFCs (LINK 
 ) 
from 40 different species or species-groups, based on recordings we've made in 
Ontario over the last few years (it is a supplement from a previous paper that 
we published in *Condor*, showing that the number of NFCs is a good predictor 
of the timing and magnitude of migration of birds through the Great Lakes).

Happy NFC listening to all on this list!

Dan

RE: [nfc-l] Unknown call -- bittern?

2016-04-27 Thread John Kearney
Hi Geoff,

There is a call of Least Bittern on the sound site, Dendroica, that is
similar to your recording. It's the last one listed on the Canadian version
of the site.

 

Thanks for raising the question about activity on this list. While I've
played an active role on the NFC Facebook group, I do think it is worth the
effort to see if this list can be re-activated. I am very engaged in
acoustic nocturnal migration monitoring and eager to know who is still doing
this and learning from their experience. There has been a recent number of
scientific papers in this field and it would be interesting to discuss the
implications and explore new ideas. In addition, there is still much to be
learned about call identification. Is anyone working on acoustic technology,
especially in the area of recording processing (detection, automated
identification, classification, and storage)? The bias of eBird toward
diurnal data poses time-consuming challenges to entering nocturnal data; can
we find a fix for this? These are some my interests, and it would be a
pleasure to hear from others.

Hi everyone,

 

I captured the attached recording at 11:39pm on April 24 in southwestern
Pennsylvania. I am wondering if this might be a Least Bittern. From what I
can find, presumed Least Bittern nocturnal calls seem to be somewhat
variable, with some higher pitched and some lower pitched, but all with a
similar nasal quality and duration that the attached recording seems to
share. This recording is certainly on the lower-pitched end of the spectrum
and doesn't completely match any Least Bittern examples I can find, though.
Thanks for any input.

 

 

I'm also posting here out of curiosity as to whether this list is still
active. It's been pretty quiet for a long time I don't mean just because it
was winter recently. Really nothing posted here last fall or so far this
spring. Has this list been more or less replaced by the NFC facebook group?

Subject: [nfc-l] flight call count and list protocols

 

Hello all,

Apropos several recent threads about eBird Nocturnal Flight Call Count 
protocol, and some confusion about how and when to use it, the eBird team 
reviewed the protocol's current description. We agreed that there was some 
potential for confusion, and we attempted to resolve points of confusion in a 
newly posted revision.  Please see this link:

 

http://help.ebird.org/customer/portal/articles/1010492-entering-nocturnal-flight-call-counts?b_id=1928

 

The important issue we are clarifying is that counts should reflect counts or 
estimates of total birds, NOT flight call counts. We are making the distinction 
between the conservative (or exact if you can do it) estimates or counts of 
birds entered in the checklist on the one hand and the species comments on 
conservative or exact counts of the calls on the other hand. These numbers, as 
you all probably know, can be related in complex relationships that are still 
unclear (although some nice work by Horton et al 2014 following up on Larkin et 
al. 2002/Farnsworth et al. 2004 sheds more light on when the relationships 
might be more interpretable).

 

A few other points of discussion from the previous emails - at present one can 
embed rich media into eBird checklists like audio via several different paths. 
In the future we expect to make this easier and an integrated part of eBird. 
Whether we will see the day that automated processing can extract information 
from such data, well, I want to say an emphatic YES! But, this will be a major 
challenge (for many reasons I am happy to discuss in a separate email). More 
likely, in the near future, we will see automated recording units that can 
provide some background information about species and call counts, hopefully 
something you'll hear more about soon.

 

Now, I would like to address some other points about list etiquette, private 
emails, and eBird reviewing. I spoke with Chris Tessaglia-Hymes, NFC-L eList 
Owner, concerning this and that we both agreed I would address these concerns 
as a representative of eBird. 

 

First, as part of this discussion, some private email conversations were posted 
to the list serve community without the knowledge or consent of all of those 
involved in the conversations. To be blunt, forwarding without consent is an 
unacceptable practice (for many reasons). This is not a practice in which we 
should engage on this list, or in any medium of communication for that matter.

 

Second, as a member of the eBird team and a reviewer, I understand that many 
times the volunteer reviewers and observers have issues communicating about one 
thing or another, and we absolutely do want this communication between the two 
parties. But in situations where conflicts and misunderstandings persist, where 
there is confusion or where there are deeper underlying issues, the appropriate 
paths to resolve these are 1) to ask for guidance from the eBird team or 2) 
with the consent of all the parties in the conversation to ask for guidance 
from the community (for example, in this case NFC list). Of course, the outcome 
of these private discussions, in private, or more public discussions, may serve 
everyone's purposes; hence the mention of the appropriate paths to resolving 
conflicts above.

 

Yes, NFC data represent a huge and largely untapped potential, but there are 
many challenges. Chris Wood, Marshall Iliff, Brian Sullivan, and I, along with 
the rest of the eBird team, will be thinking about how to streamline the review 
process for flight call data for the eBirders and the volunteer reviewers. The 
eBird review team consists of many volunteers that have the mammoth task of 
reviewing records and trying to help observers hone their eBirding skills, 
whether identification or data entry. Add to that the huge challenges in 
assessing flight call count data, because even the most versed flight call 
researchers still have fundamental and outstanding questions about species ID, 
call counts and what they mean, etc. I plan to try to 

[nfc-l] More on processing night flight calls

2013-10-07 Thread John Kearney
Hi All,

As a follow-up to Debbie's question about processing night flight calls with
Raven Pro, I recall that Laura Gooch recently raised the dilemma of the
great amount of work required in processing lower frequency, thrush-like
calls, due to traffic noise. I have a problem with ambient noise from
frequent and sustained rain and wind at one my listening sites. It is not
unusual to get 30 to 80 thousand detections in a single night. So I've been
experimenting with bandwidth filters to filter out some of the wind and rain
noise, and have had some considerable success. For the low frequency band,
I've been using a minimum bandwidth filter of 100 Hz and a maximum of 500 Hz
with energy percentile of 40%. This has reduced my detections by as much as
two-thirds or more with little change in the number of true positives. For
exceptionally bad weather, it is necessary to increase the energy percentile
to 50 or 60%. This will pull out the "loudest calls" and then you can go
back and do a more specific search for calls in the time period where these
calls were detected. 

Has anyone else used bandwidth filters in this way and would you willing to
share your findings?

RE: [nfc-l] Processing NFC recordings with Raven Pro

2013-10-07 Thread John Kearney
Hi Debbie

I sent you Raven Pro preset files as an attachment for high and low frequency 
detection that are used by the Cornell Lab (where they were given to me). 
However, if you are like me, you may not be comfortable dropping files from a 
stranger into your Raven Pro folders. So here are the parameters so you can set 
them manually.

All the best,

John

Hi John and all,

Thank you for bringing these points to the group, much appreciated. 

 

First, yes, there is an error (now corrected) - astronomical twilight should 
reference the sun's position 18 degrees below the horizon. Apologies for my 
poor editing skills! For reference, civil twilight is the sun's position 6 
degrees below horizon, nautical twilight 12 degrees, astronomical twilight 18 
degrees. 

 

Second, regarding the choice of astronomical twilight as opposed to the more 
typical civil twilight that many use for recording flight calls, we were/are 
concerned about this issue.  We spent a long time thinking about it (again) 
after you raised the point, and it is complicated in many ways (that's a topic 
for outside the NFC list serve presumably). In the end, we decided that it is 
preferred to enter NFC Count Protocol data in the period between astronomical 
twilights but it is OK to enter NFC Count Protocol beginning from civil dusk 
and concluding with civil dawn. However, please follow all the instructions 
outlined in the protocol (for example, make sure to report all other 
non-NFC-singing/calling birds as local that you detect, whether by ear or by 
automated detection)! Not that any of you wouldn't do that . . . Furthermore, 
we strongly recommend that you enter hourly or sub-hourly counts and that any 
counts entered between civil and astronomical twilight be entered separately. 
We amended the current protocol to reflect these changes and requests: 
http://ebird.org/content/ebird/about/nfc-count-protocol.

 

As with the previous posting of the protocol, please contact me with questions 
(and/or the list if NFC relevant). The original logic behind astronomical 
twilight was to separate as truly nocturnal any flight calls that were 
reported, basically eliminating the potential confusion associated with other 
crepuscular activity, increasing numbers of local species calling, and so on. 
As I said above, it's likely a topic for non-NFC list discussion as it departs 
into another realm of discussions, although I am happy to continue the 
discussion here, or privately, or offline to be summarized for the list later!

 

Hopefully this provides more clarity on some of the issues. And again, thank 
you (all) for raising this issue/set of issues! If we've not yet made it clear, 
we are eager for all in the NFC community to be involved and for those not in 
the community to join!

 

Good nocturnal birding!

Andrew (on behalf of teams BirdCast and eBird)

RE: [nfc-l] NFC protocol redux

2013-03-02 Thread John Kearney
Hi Andrew:

Thanks to you and your team for reviewing this subject. It is a very important 
and timely to develop this protocol, and your consideration of this matter is 
much appreciated. I have read the protocol a couple of times and look forward 
to begin entering my remote data in eBird. I do have one question and a comment 
concerning the definition of night (which I assume applies to both live and 
remote listening).

The protocol states: “Counts should be conducted only at night, which is 
defined as when the sun is more than 12 degrees below the horizon (the period 
between astronomical dusk and astronomical dawn).” It is quite possible that I 
may be confused on this topic, but my understanding is that astronomical dusk 
is when the sun is more than 18 degrees below the horizon. I also wonder why 
you use astronomical dusk and dawn rather than civil dusk/dawn. I would be 
interested in hearing the reasoning for this. It seems to me that it introduces 
much latitudinal bias into the data set. For example, if the peak of the spring 
Black-throated Green Warbler migration in Mobile, Alabama is in the third week 
of April, there are about 8 hours of “night” according to the definition in the 
protocol. On the other hand, during the peak of this warbler’s spring migration 
where I live in Nova Scotia, there are only 4 hours and twenty minutes of 
“night” (third week of May) under the protocol. Again, I admit that I may not 
be understanding your intention correctly. Based on nearly 18,000 night flight 
calls recorded in my location last fall, a quick estimate would be the loss of 
somewhere between 10-20% of them by restricting the report to the protocol’s 
definition of night. On some nights, the loss would be around 40%. The 
sometimes spectacular thrush descents that take place just before civil sunrise 
would also not be reportable. I would suggest that civil dusk/dawn gives a more 
complete set of data, albeit with a need to have a way to deal with some 
overlap with crepuscular land-based bird activity.

Thanks for your consideration of this issue.

John

Subject: [nfc-l] NFC protocol redux

 

Hi all,
Thank you, Laurent, Matt, Doug, Rob, and Magnus, for bringing up good questions 
and opportunities for discussion! The eBird (Marshall Iliff, Brian Sullivan, 
Chris Wood) and BirdCast (yours truly) teams reviewed this situation, your 
questions, and your comments, and we came up with some changes to the NFC 
Protocol.  We revised the NFC protocol, and you can see it here: 
http://ebird.org/content/ebird/about/nfc-count-protocol. Please take time to 
read this protocol, as it has some important points you need to know when 
submitting observations. These changes are live, so you can begin entering data 
as you see fit. I think, and we hope, that the protocol description will 
clarify questions and comments raised in previous emails. Of course, if there 
are more discussions to be had or comments, please feel free to address them to 
me privately or to the group, if appropriate.

Let me highlight a few important points:
1. Data from remote listening stations (e.g. that record while you sleep and 
that you review later, etc) are now accepted. If you would like to do this, you 
must create a SEPARATE account using the same email for your primary account 
and label the account in a very specific way (i.e. your name NFC Station). 
Please read the protocol for details.

2. We ask for as much relevant metadata for NFC protocol submissions as you can 
possibly provide. We provided a few examples in the protocol documentation.

3. Please continue to mark "N" to the "Are you reporting all species?" 
question, for now.

4. We hope to add a way for listers to mark species as "do not count on lists" 
in the future, and also to opt out of Top100, etc. This requires substantial 
development and, so, will take some time . . .

Again, please feel free to contact me to discuss this, or, if relevant to the 
NFC group as a whole, address the community.

Now . . . go out and listen, start up your gear, and program your stations . . 
. then enter all your observations into eBird!

Good birding . . . at night,
Andrew

I'm not very good at just looking at the spectrograms (and not being able to

RE: [nfc-l] ID of NFCs

2012-09-20 Thread John Kearney
In response to Wil and Charles, I do study each zeep call, by sound and
spectrogram, to make the most reasonable id possible. In a number of cases,
and at my current level of competency, I would simply be making a wild guess
as to species. Those I id to the genus level, Setophaga, since all common
zeep warblers here are of that genus except Northern Waterthrush. Especially
weak or poorly formed zeep calls may be classified only to the family level,
Parulidae. The same procedure is followed for other warbler or sparrow call
complexes.

Subject: RE: [nfc-l] ID of NFCs

 

John et al.,

 

For many purposes related to bird monitoring, recording a best-guess species
ID is better than nothing. Assigning a confidence to the ID would enhance
the value, though it will be hard to assign objectively. 

 

However, for NFC that were digitally recorded (unlike field observations),
we also have the option to archive the actual recording of the flight call,
so that any future analyst can go back and revisit the identifications and
make their own classifications. I hope that at some point in the
not-too-distant future, we'll be able to work out some sort of a web-based
database where people like yourselves who are recording NFC can upload all
the clips, along with the metadata (time, date, location, etc.). That would
allow for much greater value than simply a list of what species were
recorded on each date. Presumably most of you are keeping at least the sound
clips of each call you detected, so that when such a database is created,
you can upload them all. 

 

Andrew Farnsworth and I co-chaired a workshop at the North American
Ornithological Congress in August about acoustic monitoring, and there was a
lot of interest from multiple groups to create these types of data bases,
both for flight calls as well as other types of recording projects. We hope
that over the next year or two we'll be seeing a lot of progress.

John, I recall a post on this list serve a few years back (Mike Lanzone in
PA?) where it was mentioned that Savannah Sparrows were a common NFC, but
were rarely encountered on the ground.  I suspect given the diversity of
habitats that our migrants use, it would be really tricky to make direct
comparisons because your ground counts are so dependent on the habitat you
are in.  But it might work for certain species that you sample well on the
ground, as you say.  And of course, something like eBird that compiles
observations across sites (and skill levels, and all the other biases of
bird watching), starts to get at a more regional picture of what is expected
when.  I like the idea of probabilistic identification (and FYI, Ted Floyd
blogged about this on his ABA blog a couple months back - interesting
concept).  Maybe eBird contains the "prior" that one needs to generate
probabilities around flight call complex "identification"?

RE: [nfc-l] Northeast US: Night Migration Tonight

2012-09-10 Thread John Kearney
There have been very heavy nocturnal movements over Northern Nova Scotia the 
last few nights.

Night of September 7-8: 1,561 night flight calls recorded on the 21c of which 
about 1,300 occurred between 8 pm and midnight.

Night of September 8-9: 369 night flight calls

Night of September 9-10: 150 night flight calls

There was a good combination of thrushes, warblers, and sparrows. I’m still 
working on the analysis. These numbers may still come down a bit as I do some 
additional weeding out of noise.

I just crunched last night’s flight calls from my station in the Town Danby NY 
- a few miles south of Ithaca. 487 warbler and sparrow flight calls from 
9PM-5AM (21c/tseep-x). This is the high nightly total since this station began 
in mid-August.

 

Getting late for Mourning Warbler but I did have three probables as well as a 
few late Canadas. Three out of every hundred calls were from Wilson’s Warbler, 
which is about as good as it gets for this species in central NY. Calls 
available for download at: http://www.oldbird.org/Data/Daily.htm 

 

Also of note last night was another solid flight down the Hudson and 
Connecticut River valleys, including the first ripple of White-throated 
Sparrows (down both valleys after midnight).

[nfc-l] Nocturnal Migration in Nova Scotia

I've been conducting nightly recording and analysis of nocturnal migration
over Nova Scotia since early July. I'm posting some of my results on a

[nfc-l] July Flight Calls in Nova Scotia

2012-07-25 Thread John Kearney
I’ve been night monitoring using an Old Bird 21c since July 8th here in 
northern Nova Scotia. I’ve had a total of 163 flight calls recorded. These 
breakdown to:

79 Plovers and Sandpipers

5 Thrushes

51 Warblers

4 Sparrows

24 Miscellaneous 

 

The shorebirds are clearly migrants but I’m not sure what to make of the 
warblers. I suspect they are post-breeding birds relocating within their 
breeding landscape rather than true migrants.

The most common warbler calls have been double-banded upsweeps which I believe 
to be mostly of the genus Oreothlypis (14), followed by Yellow-rumped Warbler 
(11), and American Redstart (8).

Chris,

Thanks for taking a look at this. I think you got it. A couple other people
also suggested this species off-list.

John, 

 

This both visually and aurally is most similar to Palm Warbler NFC, of all
the species represented in the  "descending seeps" table in the Evans and
O'Brien CD-ROM.

 

Other thoughts?

 

Sincerely,

Chris T-H

RE: [nfc-l] roll call!

I have a recording station on the coast of the Northumberland Strait (Gulf
of St. Lawrence) in northern Nova Scotia. I tend to be slow on the analysis.

Can we get an update on where people are recording this spring? Is anyone
recording in Wisconsin or elsewhere in the Upper Midwest? We've had a number
of nights of moderate to heavy migration over the last two weeks and I'd be
interested to know how the night listening is going. I personally haven't
been out at night and my mic is still in a disassembled state since moving
out here at the end of December... I hope to get it up and running soon, but
in the meantime... is there anybody OUT there?

good listening!
