About Rufous-crowned sparrow in brief
The rufous-crowned sparrow is a small American sparrow. Twelve subspecies are generally recognized, though up to eighteen have been suggested. The bird has a brown back with darker streaks and gray underparts. It is primarily found across the Southwestern United States and much of the interior of Mexico. Adult sparrows are preyed upon by house cats and small raptors, while young may be taken by a range of mammals and reptiles. They have been known to live for up to three years, two months. Although the species has been classified as least concern, or unthreatened with extinction, someSubspecies are threatened by habitat destruction and one may be extinct. The American sp Sparrows are seed-eating New World birds with conical bills, brown or gray plumage, and distinctive head patterns. They live in arid scrubland, have long bills and tails in proportion to their body size as well as short, rounded wings, and build cup-shaped nests. The specific epithet is a literal derivation of the common name, derived from the Latin rufus, meaning “reddish” or “tawny”, and -ceps, from caput, meaning ‘head’ The bird is also occasionally referred to colloquially as the rock sparrow because of its preference for rocky slopes.
It has a long, rounded, brown and rounded tail, and a brown and gray face and supercilium with a thick black malar streak. The sparrow’s tail is long, with a line of contrasting color in the middle of the bird’s wingbars or a contrasting color of a contrasting line of a middle line of feathers in the back of the wing. It ranges to 25 inches in length, with males tending to be larger than females, and averages about 15 to 23 g in weight. The species is monogamous and breed during spring. Two to five eggs are laid in the bird’s nest, which is cup- shaped and well hidden. The birds are often territorial, with Males guarding their territory through song and displays. They feed primarily on seeds in the winter and insects in the spring and summer. It belongs to the family Passerellidae, which consists of the American Sparrows. It was described in 1852 by American ornithologist John Cassin as Ammodramus ruficeps. A 2008 phylogenetic analysis of the genus Aimophila divided it into four genera, with the rufOUS-c crowned sp Arrow and its two closest relatives, the Oaxaca sparrow and rusty sparrow, being maintained as the genusAimophila.
