The Tui, Prosthemadera novaeseelandiae, is an endemic passerine bird of New Zealand, one of the largest members of the diverse honeyeater family.
The name Tui is from the Maori language name tūī and is the formal common name; the plural is generally simply 'Tui' following Maori usage. The English name, Parson Bird, has fallen into disuse but came about because at first glance the Tui appears completely black except for a small tuft of white feathers at its neck and a small white wing patch, causing it to resemble a parson in religious attire.
