The Yellowhead (Mohoua ochrocephala), also known as Mohua (Maori), is a small insectivorous, passerine bird that lives in the forests of the South Island. Slightly larger than a sparrow, it has a bright yellow head, neck and breast, with the rest of the body being brownish yellow. It is a tall-forest specialist, with strong legs and a bill adapted to foraging for insects in the crevices of bark on mature trees. In the 1800s, the Yellowhead was one of the most abundant and conspicuous of our forest birds, now it is the most threatened of its genus, Mohoua, which also includes the whitehead and the brown creeper. Also known as the Bush Canary, it has a rich musical call and chatter.
