Re: [nfc-l] Clay-colored Sparrow? southwestern Pennsylvania

Hi Geoff, Another species to consider is Vesper Sparrow. Your call has the hockey stick start to the spectrogram that is typical for Vesper and separates it from White-crowned. At 74ms it is long for a Clay-colored. Paul Driver -Original Message- From: Geoff Malosh To: NFC-L

[nfc-l] American Bittern and Black-crowned Night-Heron

At 2.04am on 4/2 I recorded these two birds, which I believe are AMBI and BCNH, offering a nice comparison. Paul Driver Elkins Park, PA -- NFC-L List Info: http://www.NortheastBirding.com/NFC_WELCOME http://www.NortheastBirding.com/NFC_RULES

[nfc-l] Nocturnal finch calls

Friday night I recorded Pine Siskins several times between 3 and 5.30 am and Purple Finch at 5.20am. I was surprised to hear these supposed diurnal migrants so early. Something else of interest was Hermit Thrushes flying over with chup calls on two occasions. Paul Driver Elkins Park, PA

Re: [nfc-l] A couple of unknown calls

Bill, I suspected they were RBGR but wanted to make sure I wasn't missing anything, or over-calling weird off-key calls as all RBGR. It certainly is the "great imitator" of the nocturnal flight call world. Paul Driver Elkins Park, PA -Original Message- From: Bill Evans
