[nfc-l] huge flight last night, more to come over the next two nights
you can read my post from this morning here: http://www.woodcreeper.com/ but I think it's safe to say that calling in sick and heading to Cape May never looked so inviting. No weather is expected which would cause localized fallouts, but the promise of NW winds for the next three nights, and the northerly flow from the Canadian boreal forest all the way to NY/NJ, means that birds will be funneled down into the Cape May area by the truckload.

> and the northerly flow from the Canadian boreal forest all the way to NY/NJ, means > that birds will be funneled down into the Cape May area by the truckload. However, that assumes there's a truckload of boreal birds available to be funneled down. Over the summer I heard various reports of below average to abysmal breeding conditions in parts of the boreal (and subarctic), and as the fall migration progresses I'm increasingly inclined to believe there is some truth to them. Over the past couple of weeks, the volume of migrants at McGill Bird Observatory has been about 40% of what we experienced last year at the same time ... admittedly 2008 was a record season, but even so, I'd estimate that our recent numbers are only around 65-70% of our 5-year average. That brings me to this question - while this discussion group is new and interest in nocturnal flight monitoring is clearly growing substantially these days, no doubt some of you have been monitoring patterns for at least a few years ... if so, to what extent can you compare between years, and are you finding that the volume so far this fall seems at all different from previous years at the same time?

[nfc-l] 9/14 morning flight, Berks Co., PA
There were 45 minutes of nocturnal flight calls on nw winds from 5:30-6:15 a.m., averaging about 1/sec. at the beginning and about 3/sec. at the end. Most calls were of Swainson's and Wood Thrushes, with many fewer calls of Veery and Gray-cheeked. There was a good candidate for Bicknell's directly overhead. Also many calls of Scarlet Tanager and Rose-breasted Grosbeak. At Hawk Mt. Sanctuary's North Lookout, a rock outcrop in the Appalachian forest, the morning flight was a satisfying sensory overload and prolonged till 10:00 a.m. by cooling shreds of clouds and fog. Birders saw 19 warbler spp., with boreal warblers making their best showing so far this fall, 4 vireo spp. ( >10 Phila. Vireo alone), several flycatchers, >50 Scarlet Tanagers, ~50 Rose-breasted Grosbeaks, and many other birds. Diurnal raptors, in contrast, were scarce.

Re: [nfc-l] Call ID help. 2hrs before dawn sounds like American Goldfinch or Black Rail ?!?
Andrew,It sounds like a normal Greater Yellowlegs to me (and a great deal more probable than a flight calling Black Rail in DE). They frequently call on nocturnal migration with similar calls to those given in the daytime.

Was I missing something? I could barely hear any call at all, nevermind being able to identify it ! Sorry for my tine ear folks.

[nfc-l] 090912 Mount Pleasant cuts
Hello all, I posted to Cayugabirds about analyzing 3.25 minutes recording I did on Mount Pleasant on 091209 around 10.30 pm, when Bill Evans gave us a night flight call listening practice. I looked at spectrograms and compared with spectrograms of Bill Evans CD and I think I come close to many birds but some seem interesting. I am posting what I think they are. In 3.25 min I had 32 calls, some did not have good spectrogram as sounds were faint, but some were very good. So here are my ids of the calls, but I may be way off. They are all done manually. I was listening while looking at spectrograms. So some calls are sticking in my brain now! My ids are Chestnut-sided warbler 2 Black-throated Blue 1 Black throated green 3 Ovenbird 3 Magnolia warbler 5 Northern parula 2 American Redstart 1 Canada 1? One looks very much like Connecticut Warbler spectrogram! I may be way off but was fun looking through each and every spectrogram and try compare the energies and bandwidths. I will post the recording as MP3 in movie maker to my blog sometimes later today and if anyone is interested in seeing more spectrograms e-mail me I will send them as word files. I was just listening to another cut of 4.25 minutes that was after 11.30 PM I think and lot more interesting. May be if see something interesting i see I will post. http://meenaharibal.blogspot.com/ Happy listening!

Re: [nfc-l] Call ID help. 2hrs before dawn sounds like American Goldfinch or Black Rail ?!?
Andrew, I agree w/ Tom Johnson. However, with distant recordings not sure how you would rule out possible Lesser Yellowlegs. I have a similar call (on which I leaned towards a Greater) posted at: http://www.nightmigrants.com/main/page_species_calls_greater_yellowlegs.html Mine is also not a great recording. Xeno-canto (http://xeno-canto.org/index.php)is a good place to go to listen to flight calls from both species and if you open a call up in Quicktime, you should be able to "right click" with your mouse and "save as source" so you can save the sound file to your computer and make your own spectrograms. Hope this helps.
