The rufous-crowned sparrow (Aimophila ruficeps) is a smallish American sparrow. Isolated populations of this perching bird can be found across the Southwestern United States and much of the interior of Mexico. Twelve subspecies are generally recognized (A. r. boucardi pictured), though up to eighteen have been suggested. The bird has a brown back with darker streaks and gray underparts. The crown is rufous, and the face and supercilium are gray with a brown or rufous streak extending from each eye and a thick black malar streak. The birds are ungraceful fliers, preferring to hop along the ground. They feed primarily on seeds in the winter and insects in the spring and summer. They are often territorial, with males guarding their territory through song and displays. The birds are monogamous and breed during spring, laying two to five eggs in cup-shaped, well-hidden nests. Adult sparrows are preyed upon by house cats and small raptors, while young may be taken by a range of mammals and reptiles. Although classified as a species of least concern, some subspecies are threatened by habitat destruction, and one may be extinct.
