This morning’s little surprise (don’t you love surprises?) was this stunning Brewster’s warbler – which is a cross between a golden-winged warbler and a blue-winged warbler. Sound familiar? The bird in this post is also a hybrid, but looks like a blue-winged except for the yellow wing bars. The Brewster’s, however, has the white underparts of the golden-winged, which is a dominant genetic trait, and the eyeline and head pattern of a blue-winged, which is also a dominant trait. In any case, a gorgeous bird, don’t you think?
