Kentucky Warbler (Geothlypis formosa), Hidden Valley, Pinal County

This Kentucky Warbler was discovered and photographed by Nancy Lange on 11 May 2012.

Kentucky Warbler is a rare migrant in Arizona and is more often seen in the spring.

Unmistakable with bright yellow underparts, dark face and a conspicuous yellow supercillium which wraps around the eye.  This bird appears to be an adult female.  Adult male would have more black on the face.

Note that the most recent revision to the AOU Checklist moved Kentucky Warbler (and Mourning and MacGillivray's) out of the genus Oporornis and moved them into Geothlypis, the Yellowthroat genus.  It is therefore taxonomically more appropriate to think of this bird as "Kentucky Yellowthroat" even though its common name remains unchanged.   This leaves Connecticut Warbler as the sole member of the genus Oporonis.
