Neotropic cormorant

The Neotropic cormorant, often referred to as the olivaceous cormorant, is a medium-sized bird that flourishes in the American tropics and subtropics. These birds can be observed from the United States down through Central and South America. They breed in locations such as the Bahamas, Cuba, and Trinidad, inhabiting both coastal regions and inland waters. There are two subspecies: one inhabiting the northern range and the other residing further south. Notably, in Peru, the Uru people utilize these cormorants for fishing.

The species was first described in 1658, and Johann Friedrich Gmelin gave it its scientific name in 1789. There has been ongoing debate regarding its specific name, with some preferring Phalacrocorax olivaceus and others advocating for Phalacrocorax brasilianus.

In terms of appearance, the Neotropic cormorant measures approximately 64 cm in length with a wingspan of 100 cm. It has a slender build, distinguishing it from the larger double-crested cormorant. Its plumage is predominantly black, accented by a yellow-brown throat patch, and during the breeding season, it develops additional white tufts.

Regarding diet, the Neotropic cormorant primarily feeds on small fish but also preys on tadpoles, frogs, and aquatic insects. It dives underwater to catch its prey and often hunts in groups. Neotropic cormorants are monogamous and nest in colonies. They lay up to five bluish-white eggs, with both parents sharing the responsibility of caring for the young until they become independent.

Unlike other cormorants, the Neotropic cormorant can often be seen perching on wires. Generally, they are sedentary, although some populations migrate north during warmer months.
