Looks like Chipping Sparrow to me, perhaps two calls from the same bird - a
clue is the 80+ ms duration, but also there is a faint initial downsweep that
is structurally more in line with CHSP. Bill From: Preston Lust Sent:

[nfc-l] Nocturnal Flight Calls – Prothonotary Warbler? Last night I recorded
two calls in my yard that I believe may be prothonotary. I was wondering what
anyone else thought, or what the criteria are for prothonotary warbler in the
first place. I have attached a spectrogram of the call, as well as the
recording. Thank you very much! Preston Lust, Westport, CT--NFC-L List
