Another reason to better our understanding of the vocal activity of night
migrants.
About 7,500 birds were killed in a single night at a LNG processing plant in
Saint John, New Brunswick, Canada on the migration night of 13-14 September
2013.
Is anyone familiar with Ipswich Sparrow night flight calls and might the
attached be one?
Thanks
John
PS. The wav file is unfiltered and will sound clearer in a sound editing
program like Raven.

Hello,
I heard and recorded the attached audio in suburban Pittsburgh, Pennsylvania
about an hour before dawn on Sept. 17. An 11-second clip is attached in
which the unidentified call can be heard at about 2 sec and 9 sec. I recall
hearing it six times, five of which were picked up on
Geoff,
