Chris, Thanks! This kind of thing is very useful to those of us on the lower reaches of the learning curve. Laura --- On Thu, 10/4/12, Christopher T. Tessaglia-Hymes wrote: From: Christopher T.

[nfc-l] Mystery LF Call
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 -- Christopher T.

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

[nfc-l] sounds of morning fallout in Maine
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. http://soundcloud.com/birdwells/sounds-from-thursday-morning-1 Jeff Wells -- NFC-L List Info: http://www.NortheastBirding.com/NFC_WELCOME http://www.NortheastBirding.com/NFC_RULES http://www.NortheastBirding.com/NFC-L_SubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/nfc-l@cornell.edu/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/NFC-L 3) http://birdingonthe.net/mailinglists/NFCL.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
[nfc-l] Etna, NY: BICKNELL'S THRUSH - 10/4/2012
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!

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