Close-up of wing feathers of Anhinga, Snakebird, Darter, American darter, or Water turkey - stock photo

Extreme close-up of a male Anhinga's wing, a beautiful black and silvery white. Anhingas do not have waterproof feathers. It is believed that they do not have the oil glands to waterproof them. The structure of the anhingas feathers decreases their buoyancy and allows them to stay underwater for longer periods of time in pursuit of their prey (fish). Because their plumage is not water-repellant, they have difficulty when attempting to fly with waterlogged wings. They dry their feathers by standing with their wings spread usually under the sun.
