Neotropic Cormorants are slender, medium-sized cormorants distinguished by their long tails and thin, hooked bills. Unlike the larger and more widespread Double-crested Cormorant, Neotropics often show a white border along the base of the bill during breeding season. In Arizona, they are primarily found in the southern and central parts of the state, frequenting rivers, reservoirs, ponds, and sewage treatment plants. Their presence has increased in recent decades, especially in the Phoenix area and along the lower Colorado River. These cormorants are adept fishers, diving underwater to catch their prey, and they often perch with wings spread to dry. They have become a regular and breeding species in suitable habitats across the state.
