The anhinga (/ænˈhɪŋɡə/; Anhinga anhinga), sometimes called snakebird, darter, American darter, or water turkey, secret crow, 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. When swimming the origin of the name snakebird is apparent: only the colored neck appears above water so the bird looks like a snake ready to strike.
