Diet and Foraging

Tamaulipas Crows are omnivorous, but the diet is not well known. "Mexican Crow" (presumably including Tamaulipas Crow) is reported to be a "serious predator" on eggs and nestlings of White-winged Dove (Zenaida asiatica) in Mexico (Cottam and Trefethen 1968). The stomach of one specimen collected in south Texas contained "seeds and berries" (Arvin et al. 1975). Other observations from south Texas include crows foraging for food scraps in garbage dumps, for grasshoppers and other insects, and feeding on small animal carcasses (Didelphis) along roads (Oberholser 1974); the diet presumably is the same in Mexico, but there are few reported observation.

In captivity Tamaulipas Crows eat dog food (both dry and wet) and fruit (grapes, oranges, and small pieces of apple, but did not eat peanuts or mealworms (Webber and Hardy 1991).
