Length 16 in., wing 11 in. Theyoung bird has the forehead white, slightly speckled with brown, while both upper and under parts are dull umber. In this andother members of the genus the tail is graduated—not forked, thecentral tail-feathers being the longest. Two smaller and quitedistinct species of Noddy are also found within the tropics; whilein Polynesian and Australian waters there are yet two others, veryclosely related, but characterized by their nearly uniform grey colourand still smaller size.
