Distribution

Region

Southwest Pacific (Chatham Islands)

Typical Environment

Historically confined to forest and coastal scrub on Chatham, Pitt, and smaller nearby islands. It frequented flowering shrubs and trees for nectar, and used dense understory for nesting. Birds were most often noted at forest edges and sheltered gullies. Degradation of these habitats and the arrival of mammalian predators drove its rapid decline. No verified observations have been made since the early twentieth century.

Useful to know

The Chatham Islands bellbird (kōmako) was a honeyeater endemic to the Chatham Islands and is now extinct. It was closely related to the New Zealand bellbird but differed in plumage and voice. Rapid decline followed habitat loss and the introduction of predators such as cats and rats, with the last confirmed records from the early 1900s.

Song Description

Rich, bell-like notes delivered in clear, ringing phrases that carried through the forest. Calls included sharp chinks and softer contact notes, with a lively dawn chorus during the breeding season.
