Cassin Kingbird
448. Tyrannus vociferans. 9 inches.
These birds are very much like the last, except that the throat and breast are darker.
Derby Flycatcher
449. Pitangus sulphuratus derbianus. 10½ inches.
This is one of the largest and most handsome of the family. With its bright yellow crown, surrounded with a black border and this by white and another band of black, with the under parts a bright yellow makes him one of the most attractive. They are found, though, only on the southern borders of Texas into Central America. (Not illustrated.)
