Tui - The name Tui is from the Maori language name tūī and is the species' formal common name. The plural is simply 'Tui', following Māori 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.
