Anhinga

The anhinga’s neck, bill, and feet all help it catch prey. The neck can be bent back in an S-shape, and the powerful neck muscles, when tightened, enable the bird to thrust its head forward with great force, like a harpoon. The bill is straight, sharp, and pointed, in the form of a dagger.

Features

  • The anhinga has a small head and a long, slender neck. It uses its long and serrated bill to spear fish. Its webbed feet help it swim.
  • Males are black with greenish irridescence and adult females have a buffy neck and breast. Both sexes have silvery-white spots and streaks on wings and upper back.

Fun Facts

  • The anhinga sheds its flight feathers all at once, which makes it unable to fly for a while. During this time, it is totally silent so it doesn’t reveal its location.
  • The anhinga is also called water turkey, snake bird, or darter.
  • It swims with only its head held out of the water.
  • The anhinga’s feathers are not waterproof, so after spending some time in the water fishing, it comes out, perches on a rock or tree limb, and spreads its feathers to dry and warm in the sun.
