Whitehead

The whitehead (Mohoua albicilla; Māori: pōpokotea) is a species of small (15 cm in length, 18.5/14.5 g.) 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. Formerly quite common and widespread in native forests in the North Island, the whitehead has suffered a marked decline in the past two centuries since European colonisation and today it is restricted to a fraction of its former range. Historically, deforestation has destroyed large areas of habitat for this species but today the greatest threat is from predation by invasive mammalian species such as rats and stoats. It has been the subject of an active conservation campaign and has been successfully reintroduced into reserves near Auckland and Wellington respectively. In the past whiteheads held a special place in Māori culture.…
