The Choiseul Pigeon or Solomons Crested Pigeon (Microgoura meeki) is an extinct species of bird in the pigeon and dove family Columbidae. It was endemic to the island of Choiseul in the Solomon Islands, although there are unsubstantiated reports that it may once have lived on several nearby islands. The Choiseul Pigeon was monotypic within the genus Microgoura and had no known subspecies. Its closest living relative is believed to be the Thick-billed Ground Pigeon, and some authors have suggested that the Choiseul Pigeon may be a link between that species and the crowned pigeons. The adult pigeon was largely blue-grey, with a buffy orange belly and a distinctive slaty-blue crest. It is unknown how this crest was held by the bird in life. The bird’s head sported a blue frontal shield surrounded by black feathers and a bicoloured beak. The wings were brown and the short tail was a blackish purple. It was described as having a beautiful rising and falling whistling call. Source: Wikipedia
