#101 Black-throated Blue Warbler

Black-throated Blue Warbler (Dendroica caerulescens)

9 June

A uniquely colored, midnight-blue bird of tangled understories, the male Black-throated Blue Warbler sings a relaxed, buzzy I-am-so-la-zee on warm summer days in Eastern hardwood forests. He’s aptly named, with a midnight blue back, sharp white belly, and black throat. The olive-brown females, while not as dramatically marked as the males, have a unique white square on the wing that readily separates them from other female warblers. This warbler breeds in the East and spends the winter in the Caribbean.
