The Marquesan Imperial Pigeon is a pigeon which can be found in Nuku Hiva, the Marquesan Islands of French Polynesia. It lives in some valleys in the western part of that island. It is the biggest tree-living pigeon in the world. It weighs about 900 grams (2lb) and measures about 52 centimetres (21in).
It has broad wings and a duck-like bill. Its body is covered with dark grey feathers. It has a pair of white eyes. Its call sounds like the mooing of a cow, “waah-waah”.
It is an endangered species. There are less than 150 adult Marquesan Imperial Pigeons. Conservation efforts have been carried out to make sure that it does not go extinct.
