Tui
Prosthemadera novaeseelandiae

The Tui is a member of the honeyeater family and endemic to New Zealand. They seem to have thrived despite the introduction of predators and are quite common. The name is Maori, although in older sources, they are sometimes referred to as the Parsonbird on account of the white tufts under the neck being likened to a parson's white collar.
