Habitat

Where does it live?

At lower elevations, the anhinga prefers fresh water, usually still, sheltered waters. like lakes, ponds and marsh It requires nearby perches such as logs or low branches to dry its waterlogged feathers after feeding. It sometimes haunts brackish waters such as lagoons and mangroves.

Distribution: From North Carolina, the anhinga ranges south through the coastal states, across Central America and well into South America

Food

The Anhinga is a great fisher!

The anhinga is a piscivore. Smaller, flatter-sided, slower moving fish make up most of its diet. It also consumes crustaceans (crayfish, shrimp) and aquatic insects. In Florida, it takes caiman hatchlings

The anhinga exhibits fascinating feeding cycles. With its unique fishing technique, it dives underwater, using its sharp beak to catch fish. After surfacing, it spreads its wings to dry. This behavior, known as "wing drying," helps regulate body temperature and remove excess water. Witness the remarkable rhythm of hunting, diving, and wing drying as the anhinga gracefully navigates its aquatic world.

Reproduction

How the anhinga makes new baby anhingas

Breeding is year round in the tropics and seasonal elsewhere. In trees over or near water, anhinga nest colonially with other large water birds, often using old nests.

Courtship begins with the male performing wing waves, reverse bowing, and head swaying. To claim a nest site, he deposits twigs and does aerobatic soaring. Later he brings sticks and leaves that the female weaves into a bulky platform. After she lays 2 to 6 eggs, the pair shares the brooding for the 25 to 30 days till hatching. When switching places, they often perform recognition displays such as stretching out or entwining their necks as well as vocalizing. Males are aggressive in defending the nest. They spread their wings and snap at intruders.
