[cobirds] about that Eastern Warbling-Vireo from Teller Farms - White Rocks

Hello, Birders.

I pressed SEND too soon.

I meant to comment on the Eastern Warbling-Vireo I reported from Teller Farms - White Rocks, Boulder County, earlier this morning, Thursday, May 24th. I think it is best to refer to such birds not as "Eastern Warbling-Vireos" but rather as "birds that sound like Eastern Warbling-Vireos." For one thing, our ears (and hearts?) can deceive us: We hear one thing, and we think one thing; but then we get a danged sound recording, and the spectrogram tells us another!

And there's something else, something more insidious. How do we know it's not "really" a Western Warbling-Vireo that just happens to be singing an Eastern Warbling-Vireo's song?

The mighty Bill Maynard raises this general point in an ongoing discussion over at CFO's Facebook page:
