Coming from a leafy shrub is the pure song of a Blue-winged Warbler, just
as it sounds on your smart phone app. Searching for the songster, you find
the singing bird but it definitely not the coloration of the Blue-winged in
your field guide. Yikes! What to do?
The so-called “winged warblers” are a complex of Blue-winged
andGolden-winged Warblers and their many hybrids. They are most commonly
found in shrubby, abandoned farm fields. Two of the hybrids are known by
the names Brewster’s Warbler and Lawrence’s Warbler. Population structures
appear to be rapidly changing here in Vermont and elsewhere, and we are
trying to keep track of what is going on.
Learn more on how you can better report these to Vermont eBird. And thanks
to Ian Worley for putting this together.
