The Anhinga is sometimes called a Snakebird and is a water bird of the warmer parts of the Americas. The word anhinga comes from the Brazilian Tupi language and means devil bird or snake bird. It can swim totally under water or with its body under water and only its head and neck above.It has a pointed serrated bill to stab fish which it then flips into the air to swallow head first. Anhingas do not have oil glands to waterproof their feathers so they must perch with their wings half open to dry
