Medium-sized bright green parakeet mainly restricted to Mangere and Little Mangere Islands on the Chatham Islands of New Zealand. Note distinctive yellow crown above a red forehead. Due to hybridization with Red-crowned Parakeet, some birds have red extending to and beyond the eye and a crown that varies from yellow-orange to orange-red. Males are larger than females. Will feed out in the open on flowering flax as well as in forest habitats. Commonly seen on the ground, scratching the surface like a chicken. Chatters quietly while feeding and often calls in flight. Forms small flocks in autumn and winter. Red-crowned Parakeet is present in the same habitat but lacks yellow on crown and has an obvious red band extending to, and beyond, the eye.
