[obol] "interchangeabgle" songs, Macs & Yellowthroats

[Jay Withgott]

In response to Larry McQueen's 10 May posting:  "...I have heard some 
yellowthroats with songs
confusingly like McGillivray's, but never the reverse," and other 
postings re: song mimicry and/or similar songs....

... Same here.  Until ....  On 11 May while scouting for our Columbia 
County big day, I heard a typical "chu-witchity-witchity-witch" song 
of a Common Yellowthroat emanating from a clearcut in Washington 
County.  Except that when I looked over in that direction, it turned 
out to be a perfectly-plumaged male MacGillivray's Warbler, singing 
its little heart out, perched in full sun on a telephone wire.  Had I 
not seen it, I wouldn't have believed it wasn't a yellowthroat.
