Range and Habitat
Tamaulipas Crow: Regular visitor to extreme southern Texas from Mexico. Prefers arid country with thickets and brush such as mesquite; also ranches and farms, as well as along woodland streams.
The Tamaulipas Crow is the counterpart of the Sinaloa Crow of the Pacific slope; in fact, the two are considered conspecific by some.
The voice of this Crow is unusual and unlike most other species of the genus Corvus. It has a low croaking sound rather like a frog and a call that is described as a soft "gar-lik".
Unknown north of the U.S.-Mexico border before the 1960s, it has in recent years become a regular visitor to the Brownsville, Texas region.
A group of crows has many collective nouns, including a "cauldron", "congress", "horde", "murder", and "muster" of crows.
The Tamaulipas Crow has a large range, estimated globally at 110,000 square kilometers. Native to the United States and Mexico, this bird prefers subtropical or tropical forest ecosystems, though it can reside on arable or pastureland as well as in urban areas. The global population of this bird is estimated at 50,000 to 500,000 individuals and does not show signs of decline that would necessitate inclusion on the IUCN Red List. For this reason, the current evaluation status of the Tamaulipas Crow is Least Concern.
