The tūī (Prosthemadera novaeseelandiae) is a boisterous medium-sized bird native to New Zealand. It is blue, green, and bronze colored with a distinctive white throat tuft. It is an endemic passerine bird of New Zealand, and the only species in the genus Prosthemadera. It is one of the largest species in the diverse Australasian honeyeater family Meliphagidae, and one of two living species of that family found in New Zealand, the other being the New Zealand bellbird (Anthornis melanura). The tūī has a wide distribution in the archipelago, ranging from the subtropical Kermadec Islands to the sub-Antarctic Auckland Islands, as well as the main islands.
