Sinaloa Crow

The Sinaloa crow, a species native to western Mexico, is a bird of striking similarity to the Tamaulipas crow in appearance. Both species boast a length of 34 to 38 centimeters and share a lustrous purple-glossed, silky black plumage. Their bills, legs, and feet are also uniformly black, presenting an elegant monochrome palette.

Identification Tips

While visually akin to the Tamaulipas crow, the Sinaloa crow can be distinguished by its unique vocalizations. Observers should note the high-pitched, jay-like clarity of its calls, which stand in stark contrast to the low, gruff croaks of its Tamaulipas counterpart.

Habitat

The Sinaloa crow is found along the Pacific slope, ranging from southern Sonora to Manzanillo. It thrives in coastal regions, semi-deserts, open woodlands, riverbanks, and hills, often ascending to elevations of 300 meters or more. This crow is a familiar sight in the vicinity of coastal towns and villages.

Distribution

This species is endemic to western Mexico, with its presence confined to the Pacific slope from southern Sonora down to Manzanillo.

Diet and Feeding

The Sinaloa crow exhibits a versatile diet, foraging both on the ground and in trees. Along the seashore, it is known to turn over objects in search of food, consuming a variety of invertebrates, including small shellfish, crabs, and insects. It also partakes in a diverse selection of fruits and does not shy away from eggs and nestlings when the opportunity presents itself.

Breeding

The breeding habits of the Sinaloa crow involve nesting in thorny trees or tall coconut palms. Its nest bears resemblance to that of the American crow, albeit smaller in size.

Voice

The Sinaloa crow's call is a distinctive "ceow," high-pitched and clear, a stark contrast to the Tamaulipas crow's low, frog-like croak.

Conservation status

The Sinaloa crow is currently listed as Least Concern on the IUCN Red List, indicating that it does not face immediate threats to its survival.
