The whitehead ("Mohoua albicilla"; ) is a small species (15 cm in length, 18.5/14.5 g.) of passerine bird endemic to New Zealand. It is classified in the family Mohouidae. The male whitehead's upperparts, wings and tail are a pale brown in colour, while the head and underparts are white – in the case of the male an almost pure white in colour. Females and juveniles have similar colouration except that the nape and crown (top of the head) are shaded brown. The black beak and eyes contrast with the white head and the feet are bluish black in colouration.
