White-crowned Forktail

The white-crowned forktail is a species of forktail in the family Muscicapidae. Formally described in 1818, it has five subspecies, each occupying a different geographic range. The largest of the forktails, Enicurus leschenaulti, is between 25 and 28 centimetres long. It has a black throat and breast, black mantle, and largely black wings. The rump and lower back are white, and the bird has a prominent white crown, from which it gets its name. As with other forktails, the tail is long, deeply forked, and banded in black and white. A variety of whistling and clicking calls have been described. Slight morphological differences have been observed between subspecies.
