New Zealand Pigeon

Descrizione

The kererū (Hemiphaga novaeseelandiae), also known as kūkupa (northern Māori dialects), New Zealand pigeon or wood pigeon, is a species of pigeon native to New Zealand. Johann Friedrich Gmelin described the bird in 1789 as a large, conspicuous pigeon up to 50 cm (20 in) in length and 550–850 g (19–30 oz) in weight, with a white breast and iridescent green–blue plumage. Two subspecies have been recognised; the second—the Norfolk pigeon of Norfolk Island—became extinct in the early 20th century. Kererū pairs are monogamous, breeding over successive seasons and remaining together when not breeding. They construct nests with twigs in trees, with a single egg clutch. Found in a variety of habitats across the country, the kererū feeds mainly on fruits, as well as leaves, buds and flowers. Although widespread in both forest and urban habitats, its numbers have declined significantly since European colonisation and the arrival of invasive mammals such as rats, stoats and possums. However, the results of nationwide bird surveys indicate that there has been a significant recovery in the population in suburban areas. As of 2022, the IUCN Red List classifies the species as least concern, while the Department of Conservation (DOC) classifies the kererū as "not threatened" but conservation dependent. Considered a taonga (cultural treasure) to the Māori people, the kererū was historically a major food source in Māori culture.
