Last night, I recorded a few distant unusual-sounding screams (unfamiliar to me 
at my recording location), the loudest and closest of which sounds and 
spectrographically looks like a very near match for BARN OWL. This is an 
extremely rare migrant through Upstate, NY. I would appreciate any input from 
other NFC listeners.

What is interesting is that Jay McGowan heard a likely Barn Owl over his place 
in Ithaca on 27 July.

This bird was calling at 23:54 last night (1 August). It is possible that birds 
are passing through the area, or that there is a single bird moving around the 
area. Not knowing much about their behavior at this time of year, as far as 
local movement, makes me think more the former, that there were two 
coincidental migrants a few days apart.

This sound is more evenly raspy sounding and less "question-like" sounding than 
an immature Great Horned Owl call. The sound also falls nicely around the 2kHz 
frequency band, which is consistent with the examples provided on the Evans and 
O'Brien CD-ROM.

Attached is a clip of the best sound (thus far � I am still going through data) 
as well as a screen grab of the call.

Thanks for any input!
