About Corvus imparatus J.L.Peters, 1929
Corvus imparatus J.L.Peters, 1929 is a relatively small, sleek crow, measuring 34–38 centimetres (13–15 inches) in length. It has very glossy dark bluish plumage that appears soft and silky. Its bill is quite slender and black, and its legs and feet are also black. The only other crow that this species commonly occurs alongside is the much larger, very different Chihuahuan raven. This crow occurs in a relatively small area in northeastern Mexico, where it inhabits near-desert scrub and bushland; its range also includes farms, small towns, and villages. It can also be found in more humid open woodland, but it does not occur in higher mountains or along the seashore. It is a sociable bird that often forms large flocks and travels together in close groups. Its northern range extends to Brownsville in southern Texas, where it is known to nest.
