Gray Catbird

Adults weigh around 35–40 g (1.2–1.4 oz)[3] and are plain lead gray almost all over. The top of the head is darker. The undertail coverts are rust-colored and the remiges and rectrices are black, some with white borders. The slim bill, the eyes, and the legs and feet are also blackish. Males and females cannot be distinguished by their looks; different behaviours in the breeding season is usually the only clue to the observer. Juveniles are even plainer in coloration, with buffy undertail coverts.
