Why do Anhingas stand with their wings open in the sun?

Like cormorants, the anhinga stands with wings spread and feathers fanned open in a semicircular shape to dry its feathers and absorb heat. They face away from the sun to dry their feathers.

Are Anhingas rare?

Anhingas are uncommon throughout their range and they reside in areas that can be difficult to reach, thus obtaining a relatively accurate estimate of their population is difficult. The best available estimate of their population comes from the North American Breeding Bird Survey and Partners in Flight.

Why do Anhingas dry their wings?

The structure of cormorant and Anhinga feathers decreases buoyancy and thus facilitates underwater pursuit of fishes. Hence their plumage is not water-repellent, but “wettable.” It has been suggested that the function of the spread-wing postures in these birds is to dry the wings after wetting.

How does an Anhinga Thermoregulate?

So, how do Anhingas thermoregulate? These birds thermoregulate by perching on an open area, spreading their wings, and turning their back to the sun. By doing this, they are functionally turning the dark-colored feathers on their back and wings into solar panels, absorbing as much radiation as possible.

Can the Anhinga fly with wet wings?

An anhinga with wet wings has difficulty flying. It can do little more than skip along the water’s surface while madly flapping its wings.

How long can Anhingas stay underwater?

Feeding: Cormorants may hunt and fish alone or with flocks of several hundred birds. They dive up to 60 feet and can stay underwater for more than a minute, swimming using webbed feet. They eat mostly fish and invertebrates like crayfish.

Are anhingas native to Florida?

Birds in Mexico perform a particular display when they are at the nest, vocalizing to each other, stretching their neck towards their mate.
