All,
I had been privy to this clip earlier when there were internal discussions about it within Cornell. Perhaps I should have chimed in then, when the group was smaller and the chance at sounding foolish lessened, but I'll go ahead a stick my neck out now, ready to be guillotined by the rest of the group. This doesn't quite sound right for White-eyed Vireo to me. I listened to it a bunch of times and was never convinced that it wasn't the tail segment of an Ovenbird flight song. The beginning seems to wavering and not explosive enough and the end of the song does not have the abrupt chip that White-eyed almost always has. It sounds like this song may have been picked up in the middle-Steve do you have a longer cut including the 5 seconds before this clip? I'll admit to some amount of bias that I think White-eyed Vireo is an unlikely migrant to hear singing in flight AND even less likely to be recorded in Ithaca, versus somewhere in their regular breeding range. But part of why this NFC stuff is so interesting is that it can challenge our ground-based assumptions. Any thoughts on the possibility of the tail end of Ovenbird flight song as an alternate ID?
