Blue-headed Vireos Begin Migration
Blue-headed Vireos (formerly called Solitary Vireos) are fairly distinctive birds, given their white “spectacles” or eye-rings. (Trying to make their heads blue seems to be a bit of a stretch, however.) They are the latest species of vireo to migrate, beginning about now and peaking at the end of September/beginning of October. After spending the winter in southern U.S. or Central America, they will head north, one to two weeks earlier than any other species of vireo.
