SETOPHAGA, Swain son. 
Setophaga, Swainson, Zool. Jour. Ill, Dec. 1827, 3G0. Type Muscicapa ruticilla, Linn. 
Sylvama, Nuttall, Man. Orn. I, 1832. Type Muscicapa ruticilla. 
Ch. — Bill depressed ; broader than high ; rictus with long bristles. Wings rounded, equal to or shorter than the tail; first 
quill sh' rter lhan the fourth. Tail long; somewhat graduated, the outer feathers about .20 of an inch or more shorter; all the 
feathers unusually broad, and widened at the end. Feet short; tarsus shorter than the head. Hind toe equal to the lateral. 
Coloration embracing more or less of red in northern species. 
This genus differs from Myiodioctes chiefly in the longer broader tail, and rather shorter tarsi 
and toes, the hinder especially. The bill is more muscicapine ; the culmen nearly straight to 
the abruptly decurved and much notched tip ; the gonys straight. In Myiodioctes the vertical 
outlines are more convex ; the gonys more ascending ; the tip gently and but slightly 
decurved. 
The species of this genus are all characterized by the brilliant red, yellow, black, &c, of 
their plumage, and, according to Kaup, (Pr. Zool. Soc. 1851, 49,) may be divided into 
geographical groups, characterized by the prevalence of particular colors. The South American 
species have more or less of yellow. The Mexican are usually black and red, without any pure 
yellow.
