The
yellow-throated warbler is not often seen at Magee Marsh, but when it
is seen it's during the first half of May. The bird is very
striking with the strong black-and-white markings on the face and the
bright yellow throat. The Kentucky
warbler has a similar black patch on the face but lacks the white
and has more extensive yellow on the underside. The yellow-throated vireo is quite
different, since it has no black on the face. The common yellowthroat has a black
face patch that runs continuously from one side of the face to the
other, and has a brown back and head rather than the blue-gray of the
yellow-throated warbler.
