The New Zealand Pigeon grows to some 51 cm (20 inches) in length and 650 grams in weight. The head, throat and wings are generally a shiny green-purple colour, but with a bronze tinge to the feathers. The breast is typically white and the bill red with an orange-ish tip.  Their wings make a very distinctive "whooshing" sound as they fly.  Māori call it Kererū.
