[nfc-l] Etna, NY: Dickcissel - 10/4/2012

2012-10-04 Thread Christopher T. Tessaglia-Hymes
Toward the end of a fairly good stream of migrants overnight, early this 
morning at 4:04AM, a single Dickcissel was audible calling once while passing 
over my listening station in Etna, NY.

Attached is an edited sound file of the call. I had to filter out the cricket 
band and amplify the call slightly.

Good night listening!

Sincerely,
Chris T-H

[nfc-l] Etna, NY: BICKNELL'S THRUSH - 10/4/2012

2012-10-04 Thread Christopher T. Tessaglia-Hymes
During the morning descent of thrushes calling, I was pleasantly surprised to 
record another nice example of a BICKNELL'S THRUSH flight call. This bird 
called at 6:29AM.

This bird's call peaks out at about 5.23kHz, well above any Gray-cheeked Thrush 
NFC that I've seen. Most of the Gray-cheeked Thrush flight calls that I have 
recorded, peak out in the 3.5-4.5kHz frequency band, with a very occasional 
call that might peak out every so slightly above 4.5kHz.

The overall duration of this call is shorter than the one from the other night, 
this lasting only 208ms.

The quality and timbre of the call is likened to a much higher-pitched and 
wheezy-sounding "Gray-cheeked Thrush".

An edited copy of the call is attached, again to remove the cricket band and 
slightly amplify the sound.

A screen grab of the call is also attached.

Good night listening!

Sincerely,
Chris T-H

[nfc-l] sounds of morning fallout in Maine

2012-10-04 Thread Jeff Wells
This morning at 5 when I stepped out of our house in Gardiner, Maine 
(south-central Maine about 30 miles from coast) in the dark, the sky was filled 
with flight calls of birds (low ceiling, intermittent light showers). Using my 
iPhone I made a 5 minute recording of what it sounded like if anyone is 
interested (link below). Sadly, I was not running my audio station

Haven't gone through really carefully but includes Hermit Thrushes, Swainson's 
Thrushes, Savannah Sparrows, Yellow-rumped Warblers, White-throated Sparrows, a 
Common Yellowthroat, perhaps a couple of Swamp/Lincoln's Sparrows and I'm sure 
some other things too.

[nfc-l] help with sparrow from Sept. 25

2012-10-04 Thread Caleb Putnam
All-

I could use some help on this recording from my house in Sand Lake, MI at
2346 hrs on September 25, 2012. It was made with Bill Evans's 21c
microphone.

Audio:
http://soundcloud.com/user9140545/sparrow-sp-sep-25-2012-2346

Sonogram:
http://www.flickr.com/photos/27846187@N07/8054073788/

The bird was lateral to the microphone a fair ways, perhaps 100m, and so
the signal was not picked up as strongly as I had hoped. I was listening on
my roof at the time and immediately recognized this as different from the
numerous Savannah Sparrows which were flying that night, mainly because of
the longer duration note. Depending on how you measure it, it appears to be
about 0.15-0.18 seconds long, but I am not clear that the end of the note
wasn't cut off due to the poor recording (?) since the bottom band gets
'fuzzy'. I immediately suspected Nelson's (NESP) or Le Conte's Sparrow
(LCSP), but the bands don't appear as parallel as the ones for LCSP in
Evans and O'Brien (Flight Calls of Migratory Birds) and are not a perfect
match for any of the NESP/LCSP recordings I see there. They do seem close
to the Fig. 6 recording for NESP from April 26, 1989 in Florida (listed as
hypothetical).

Can any progress be made on this one, or shall I best leave it as sparrow
sp.? Or can I confidently call it an Ammodramus sp., or even Le
Conte's/Nelson's?

Thanks,
Caleb

[nfc-l] Mystery LF Call

2012-10-04 Thread Christopher T. Tessaglia-Hymes
The following call has me temporarily stumped. It was definitely a transiting 
bird in the sky, as it called again a few moments later, but clearly farther 
away. It has certain rail-like qualities or perhaps tern- or shorebird-like 
qualities.

Thoughts?

Thanks!

Sincerely,
Chris T-H

Chris,

Thanks! This kind of thing is very useful to those of us on the lower reaches 
of the learning curve.
