Distribution

Sinaloa Crow is endemic to northwestern Mexico. It occurs along the coastal plain and the lower Pacific slope from southern Sonora south to Nayarit, and east to western Durango (Miller et al. 1957, Howell and Webb 1995, Russell and Monson 1998). A report that Sinaloa Crow is recorded from Colima (Miller at al. 1957) is in error (Schaldach 1963). Miller et al. (1957) also report that Sinaloa Crow is "casual" on María Madre Island, but this species was not mentioned as occurring at all on the Tres Marías group by Stager (1957) or Grant and Cowan (1964), and Howell and Webb (1995) consider its presence there to be "probably also erroneous".

The elevational range of Sinaloa Crow is from sea level up to 1000 m (Howell and Webb 1995).

Endemic to the Americas.

Sinaloa Crows occupy towns and villages, associated refuse dumps, agricultural areas, and other open and semiopen habitats. Davis (1958) described Sinaloa Crows occurring "on wet sand of the sea beach when the tide is out and along river estuaries", but van Rossem (1945) reported that this species avoids "maritime associations", as well as avoiding deserts.

None reported (in contrast to the recent range expansion of Tamaulipas Crow Corvus imparatus), although Russell and Monson (1998) note that the population of Sinaloa Crow has increased in southern Sonora in recent years, "probably attributable to an increase in the extent of agricultural lands as irrigation waster has become more widely available".

None reported.
