All, About fifteen years ago, in central Ohio, a birder friend and I observed a phenotypic Golden-winged Warbler sing a spot-on typical Blue-winged Warbler "bee-buzzz" song at point-blank range in a low tree. Although we both had read of this, it was the first time that we had actually witnessed it. As anyone who knows me knows, I am at least as much an ear-birder as an eye-birder, especially in regard to passerines. This BWWA/GWWA phenomenon remains truly surprising to me, as I can usually use subtle details of tone, phrasing, structure, etc. to distinguish similar sounds and different species. (I am a former musician of dubious accomplishment who retained an ear but not much else.) Moral of the story: know the limits of ear-birding and eye-birding, and proceed with caution.

I thought you'd like to know.

For a good thirty minutes I listened to a bird singing a typical Type I Blue-winged Warbler song (beee-buzzzzzz). I'm familiar with the songs of the Golden-winged Warbler (which I also heard this morning) and Blue-winged Warbler. I would call it 100% Blue-winged, but never actually got a look at the bird. Golden-winged Warblers occur regularly in this area, but both the Blue-winged Warbler and hybrids have been observed here. The bird was along the right side of the entrance road between the old house ruins and the first big, red gate you encounter as you follow the trail up into the cove. Habitat was open with small trees and scattered blackberry. Rick -- Rick Phillips Kingsport, Tennessee </blockquote> -- Rick Phillips Kingsport, Tennessee
