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

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.

I’ve been listening live in Etna, NY tonight since 10:30pm. This has been an

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

and Flowrabola microphone.) 



















Good night-listening!

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.

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!

Hi Chris,

How wonderful to be listening in live!I haven't been listening
continuously, but whenever I've tuned in this evening I've heard a steady
stream of flight calls. I'd imagine when I get around to tallying them up,
it will be in the thousands.

Happy Listening,

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

2020-09-17 Thread Kenneth V. Rosenberg
Hi Chris et al.,

I was also out listening in Ithaca continuously from about 10:30 to 12:30 
tonight, and I agree it was a fantastic night – still going on, but I’m not. It 
is true that there calls nearly every second for several hours.  I just listen 
and count in real time, assigning the birds I think I know, and putting the 
rest as warbler sp. or passerine sp.  In this period, I counted > 1,000 calls 
of 15 species, the vast majority SWTH and without differentiating any warblers 
other than Common Yellowthroat. I’m sure if I was amplifying or recording, I 
would have thousands more calls, as Chris did.

My highlights were a flock of Caspian Terns calling together, an American 
Bittern, good numbers of Gray-cheeked and several early Hermit Thrush, and a 
totally unexpected BARN OWL that called 4 times as it headed north over my 
neighborhood – I got a pretty good recording on one call on my phone, which 
I’ll upload eventually.

Fun stuff!

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.
