Anhingas are large water birds known for their long necks and tails, often referred to as "snakebirds" due to their swimming style, where only their necks are visible above water. They primarily inhabit warm, shallow waters and are skilled at catching fish with their sharp, daggerlike bills.
Overview of Anhingas
Anhingas, also known as snakebirds or water turkeys, are large water birds belonging to the family Anhingidae. They are primarily found in warm, shallow waters across the Americas. The name "anhinga" comes from the Tupi language, meaning "devil bird" or "snake bird," which reflects their unique swimming style where only their necks are visible above water.
Physical Characteristics
Size and Appearance
- Length: 29.5 to 37.4 inches (75 to 95 cm)
- Wingspan: Approximately 42.9 inches (109 cm)
- Weight: 2.3 to 3.0 pounds (1.04 to 1.35 kg)
Adult males are glossy black with silver-white streaks, while females have a lighter tan head and neck. Both sexes have long, slender bodies and a distinctive long tail.
Habitat and Behavior
Anhingas inhabit freshwater lakes, ponds, and slow-moving rivers, often perching on branches to dry their wings after swimming. They are known for their unique hunting technique, using their sharp beaks to spear fish and other small aquatic prey. Unlike many water birds, anhingas do not have waterproof feathers, allowing them to dive underwater effectively.
Nesting and Migration
Anhingas typically nest in colonies with other birds like herons and cormorants. They build nests in trees near water, using sticks and leaves. While some anhingas migrate based on temperature, many remain in their habitats year-round, especially in warmer regions like Florida and parts of South America.
