The Four Keys to ID

  • Size & Shape

    Anhingas are large and slender waterbirds with long fanlike tails that resemble a turkey's tail. They have a long S-shaped neck and a daggerlike bill. In flight, Anhingas look like a flying cross; the wings are held out flat and the neck and tail stick straight out. They have slim bodies and look rather flattened in flight.
