Re: [nfc-l] Possible Dickcissel NFC

[Ethan Duke]

Although anyone would be aghast if I were to claim a level of expertise near 
that of Ken or Bill, I’d include EAME in the clade exhibiting flatulence. In 
any event, it is a shame that those Dickcissels get crop-dusted on their 
wintering grounds.
 
Removing myself from the room,

David,


This certainly sounds similar to the Ovenbird flight songs that I've heard while in the field before. I love how they seem to throw in snippets from the songs of a few neighboring species into their flight song. Don't know if they pick these song snippets
 up over time or if they add them in based upon what they hear from the nest or at their breeding locales. I usually pick up Red-eyed Vireo snippets more readily than other sound snippets in my past experience, but that may be entirely locale-related. It certainly
 helps to be able to replay the sounds over and over again.


The first one seems to have the following makeup:


Unidentified Chips, Winter Wren, Common Yellowthroat, OVENBIRD, Unknown, Black-capped Chickadee, American Robin, OVENBIRD, Northern Waterthrush, Unknown, Red-eyed Vireo, Unknown.


The second one seems to have the following makeup:


Unidentified Chips, Winter Wren, Common Yellowthroat, OVENBIRD, Unknown, Black-capped Chickadee, American Robin, Red-eyed Vireo, Northern Waterthrush, Unknown.


I suspect these are likely from the same individual, just a slightly different combination.


Very cool!

On July 17 I set up a migration mic at Thacher Nature Center near Albany, NY.  That night I recorded what I think is the so-called flight song of the Ovenbird, which I have heard only once or twice before.   I recorded a very similar
 song on 19 July.  I've been digging around trying to find examples, and the flight song seems to be extremely variable among birds.

I've posted the recordings and sonograms at 
http://naturebits.org/temp_1.php

I'd be interested in any comments.  If it is not an ovenbird, what is it?

Re: [nfc-l] Flight Call Exemplar Database?

[Ethan Duke]

YES!! I agree. It would be great to add some sort of credit to whomever built the detector that located the call and possibly the parameters used. This could be placed in the remarks section of xeno-canto.Side note: Just returned from a distance sampling workshop with a passive acoustics component. I have materials on this for anyone wishing to know more.Ethan

I'm thinking of a flight call database that is accessible to anyone for easily uploading contributions, like
http://www.Xeno-Canto.org. If so, is a there a projected release time-frame?


So many people are out there collecting voluminous NFC data. It would be great to get the best-of-the-best of these examples, especially examples of non-North American flight calls, into an easily useable and accessible sound library of sorts.


Thoughts?


Thanks!

Re: [nfc-l] Hermit Thrush flight calls on ground

Chris,

It definitely seems more likely that it is on the high end of the motivation 
spectrum. Seems like a long shot for a flight vocalization.

Thanks!

Re: [nfc-l] big night flight tonight

[Ethan Duke]

Is the Alfred listing station (not to be confused with "Alfred Station", a 
nearby hamlet), on Jericho Hill. This would give it significant elevation. 
Could elevation be a factor effecting 2?
Just another thought. By the way. I don't usually post much and there may be 
others on this list who are passively learning a TON from those who do. Posts 
and assistance from those on this list are greatly appreciated.

FYI... We have had a few pulses of activity here in Missouri. Generally, more 
activity has be seen on the ground (mist-netting) and through visual 
observations. My Fall 2011 NFC placement is horrible (too close to insects of 
all sorts singing in every frequency range) and I'll be moving it soon. So far 
we've had steady small numbers of migrants moving through. AHY warblers, 
tanagers, RBGRs, have been on the move here for the past week.

Re: [nfc-l] odd NEXRAD pattern

[Ethan Duke]

I haven't seen the radar for central Missouri. I'm honestly still trying to 
understand how to use it well. We are west of Columbia and East of Kansas City 
on the Missouri River. A large wave of migrants reached our banding station 
today (Daily Total: 90 birds, 28 species). Half of the birds (n=43) were 
Yellow-rumped warblers (MYWA). Productivity increased throughout the morning. 
Preliminary NFC recording screening showed very little pre-sunrise activity.

South winds over the weekend brought a smaller wave of migrants (with extremely 
low fat and muscle scores). This latest wave was in a little better condition.

[nfc-l] detectors

[Ethan Duke]

Greetings All,

I found a 2009 post from Mike Powers with a couple detectors attached (Sparrows 
and Thrushes). Altruism is alive and well. Are there any others available?

FYI, we are are on our third night of deployment of SM2 at Grand Pass 
Conservation Area along the Missouri River in central Missouri. It is recording 
next to our array of 21 nets. Yesterday we captured 31 birds (RCKI, SWSP, and 
WTSP dominating the mix). Not too many flight calls, yet.

Thanks,
Ethan
