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.

Subject: [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!
