Formerly treated as conspecific with Sinaloa Crow (Corvus sinaloae) under the name Mexican Crow, Tamaulipas Crow is fundamentally endemic to northeast Mexico, although it is regularly recorded in the southernmost corner of the United States, in southeast Texas, principally during the nonbreeding season. This small, slender crow’s plumage is entirely black, but is glossed purple, blue, and green. Morphologically it differs from Sinaloa Crow solely in having a slightly shorter tail. However, its lower-pitched vocalizations and genetic distance appear to confirm the split from the Sinaloa Crow. Tamaulipas Crow is generally found below 300 m, where it inhabits scrubby farmland and open woodland, as well as habitation, where it regularly attends rubbish dumps.
