Recorded this morning (6 am) in Andorra Natural Area, Philadelphia.
I thought for sure that it was a Black-And-White Warbler this morning when I heard it. But then I'm completely stumped when I compare the sonogram to known American Redstart and Black-And-White Warbler.
The sonagrams don't look like either standard A. Redstart or Black-and-White Warbler sonagrams.
Number of repeats - more like A. Redstart
Pitch - more like Warbler
Quality - more like BW Warbler
I have a better recording than the one I posted earlier where the bird sings multiple times: 8 secs, 11 secs, 16 secs, 24 secs, 31 secs

Here is a sonagram at 8 secs:
11 secs:
16 secs
24 secs
31 secs

It was at the top of a tree. There are plenty of Redstarts breeding in the area, but I haven't seen any BW Warblers since migration.

*WMA seems to work for most people, I also have it as a larger mp3 file.
