Rhynochetos jubatus (Kagu)

Wikipedia Abstract

The kagu or cagou (Rhynochetos jubatus) is a crested, long-legged, and bluish-grey bird endemic to the dense mountain forests of New Caledonia. It is the only surviving member of the genus Rhynochetos and the family Rhynochetidae, although a second species has been described from the fossil record. Measuring 55 cm (22 in) in length, it has pale grey plumage and bright red legs. Its 'nasal corns' are a unique feature not shared with any other bird. Almost flightless, it spends its time on or near the ground, where it hunts its invertebrate prey, and builds a nest of sticks on the forest floor. Both parents share incubation of a single egg, as well as rearing the chick. It has proven vulnerable to introduced predators, and is threatened with extinction.

EDGE Analysis

The Kagu is a highly unusual, almost flightless bird, which due to its startling ash-white plumage, is known locally as the ‘ghost of the forest’. The only representative of an entire taxonomic family, the Kagu resembles something between a small heron and a rail. It has a large crest, long legs, a peculiar ‘bark’, which can be heard over a mile away. It is endemic to Grand Terre, the largest island of New Caledonia and has been adopted as the national emblem. Sadly, following predation by dogs and habitat loss the Kagu is now listed as Endangered. The Kagu experienced a decline in numbers during the 1900s primarily due to predation by invasive species. Domestic dogs have historically been the main threat to the species along with cats and pigs.
