"r'rauh", "ruuh'aah"
Unlike other cormorants, the Neotropic Cormorant can often be seen perching on wires.
The northern populations are often called Mexican or Olivaceous Cormorants, and many authors treat these as a separate species, P. olivaceus.
Those who say the entire population is a single species treat the northern birds as a subspecies Phalacrocorax brasilianus mexicanus and the southern birds as subspecies P. b. brasilianus.
A group of cormorants has many collective nouns, including a "flight", "gulp", "rookery", "sunning", and "swim" of cormorants.

● Song: "r'rauh", "ruuh'aah"
● Foraging & Feeding: Neotropic Cormorant: Feeds on variety of fish, frogs, tadpoles and other aquatic organisms. Dives in pursuit of prey from water's surface. The only cormorant known to occasionally plunge dive from above water's surface. Cooperative feeding has also been documented.
● Breeding & nesting: Neotropic Cormorant: Monogamous and colonial. Male chooses nest site and brings materials to female who builds nest in the fork of a tree, rarely on ground. Nest is made of sticks, twigs, grasses, and leaves. Both sexes incubate two to six pale blue eggs for 23 to 26 days and tend young who become independent around 11 weeks.
● Similar species: Neotropic Cormorant: Double-crested Cormorant is larger and heavier looking, has a shorter tail, a yellow-orange throat pouch, and a green sheen on head, neck, and underparts. Brandt's Cormorant is seen on the West Coast, has a shorter tail, and a blue throat pouch during breeding season.
