Genus SPERMOPHILA, Swainson.
Spermophila, Swainson, Zoöl. Jour. III, Nov. 1827, 348. (Type, Pyrrhula falcirostris, Temm. Sufficiently distinct from Spermophilus, F. Cuv. 1822.)
Sporophila, Cabanis, Mus. Hein. 1851, 148. (Type, Fringilla hypoleuca, Licht.)
Spermophila moreleti.
30524 ♂
Gen. Char. Bill very short and very much curved, as in Pyrrhula, almost as deep as long; the commissure concave, abruptly bent towards the end. Tarsus about equal to middle toe; inner toe rather the longer (?), reaching about to the base of the middle one; hind toe to the middle of this claw. Wings short, reaching over the posterior third of the exposed part of the tail; the tertiaries gradually longer than the secondaries, neither much shorter than the primaries, which are graduated, and but little different in length, the first shorter than the sixth, the second and fourth equal. The tail is about as long as the wings, rounded, all the feathers slightly graduated, rather sharply acuminate and decidedly mucronate. Smallest of American passerine birds.
The essential characters of this genus are the small, very convex bill, as high as long; the short broad wings, with the quills differing little in length, the outer ones graduated; the tail as long as the wings, widened towards the end, and slightly graduated, with the acuminate and mucronate tip to the feathers.
Many species of the genus occur in Middle and South America, although none not readily distinguishable from the single North American one.
