Darter

Darter, any bird of the genus Plotus of the Pelican family, with four species, South America, Africa, India, and Australia each having a characteristic one. These birds are about 3 feet long, with dark plumage marked and dotted with white. The neck is very long and flexible, whence they are sometimes called snake-necks. They nest and perch on trees near running water, whence they swoop down with great dexterity on fish, which forms their chief food.
