Sinaloa Crow
Corvus sinaloae
The Sinaloa crow is 35.5 to 38 cm (14 to 15 in) long; two individuals weighed 229 and 258 g (8.1 and 9.1 oz). The sexes have the same plumage, which is nearly identical to that of the Tamaulipas crow. Adults have glossy dark violet crown, nape, secondary wing coverts, and secondaries. The sides of their neck and their back, scapulars, rump, uppertail coverts, and primary coverts are glossy dark violet blue. Their primaries and rectrices are dark steel blue with a greenish tinge on the outer primaries and a violet tinge on the central rectrices. Voice: The Sinaloa crow's voice is the characteristic that led to its recognition as a species separate from the Tamaulipas crow. The Tamaulipas crow's voice is burry or croaking, characters absent from that of the Sinaloa crow.
