This species of Kingfisher is endemic to Mangaia Island, the southern most Cook Island. Despite it’s relations, this species does not usually eat fish. Most of its diet consists of lizards and skinks. This species’ mating habits are also different than most, they often breed in pairs or trios and switch between polygyny, polyandry, and monogamy. Because the Mangaia Kingfisher is endemic, it is vulnerable to introduced species and habitat fragmentation. More than half of the Cook Islands’ endemic land birds are extinct and better management of land resources can reduce the threat of extinction for birds like the Kingfisher.
