Anhingas: Unique Waterfowl with Snake-like Necks and Fascinating Behaviors

Anhingas, medium-small waterfowl belonging to the family Anhingidae, average about 35 inches in length. Known for their long, snake-like necks and pointed yellow bills, these birds inhabit warm wetlands and the edges of ponds, lakes, and rivers. Their diet mainly consists of fish, crayfish, and frogs, which they catch by spearing and flicking into the air. While solitary during the day, they roost in colonies at night. Anhingas lay bluish-white, speckled eggs, with both parents sharing incubation duties. Chicks are altricial, reaching full maturity by around three years.
