The grey-winged trumpeter (''Psophia crepitans'') is a member of a small family of birds, the Psophiidae. It is found in the northern Amazon rainforest and Guiana Shield in tropical South America. Unlike all other trumpeters, the rump and back are grey in the grey-winged trumpeter. It has two subspecies separated by the Rio Negro: The nominate from the Guiana Shield, and ''napensis'' from the north-western Amazon. Although their plumage differences are relatively minor, some have suggested they should be treated as separate species (instead of subspecies) due to genetic differences.〔Ribas, Aleixo, Nogueira, Miyaki and Cracraft. 2011. A palaeobiogeographic model for biotic diversification within Amazonia over the past three million years. Proceedings of the Royal Society〕 Genetic evidence also suggests ''ochroptera'', traditionally considered a subspecies of the pale-winged trumpeter, actually is closer to the grey-winged trumpeter.〔 The grey-winged trumpeter is a dumpy, guineafowl-like bird with a long neck and legs, and short yellow chicken-like bill. It is long and in weight. The soft plumage is mainly black, but the feathers of the inner wing are grey. These are gregarious forest birds which nest in hollow trees, laying 3-4 white eggs that are incubated by all members of a group of five or more birds. When not breeding, the flocks may number 50 or more. Their food is insects and fruit, picked off the ground. They are weak fliers, and will run by preference. The grey-winged trumpeter's song is a low humming, but its call, as its name suggests, is a very loud ''JEEK'' or honking ''TZAAK''. This bird is kept as a pet by Amerindians, since it is easily tamed, hunts snakes, and is a very efficient sentinel, with its unmissable alarm call. A captive grey-winged trumpeter named ''Trumpy'' was kept at Jersey Zoo by the author Gerald Durrell, and was noted for interacting with the people and animals of the zoo. "Trumpy" is mentioned several times in Durrell's book "Menagerie Manor". ==Gallery== Image:Grey-wing Turmpeter RWD.jpg|Jacksonville Zoo, Florida Image:Grey-winged Trumpeter Psophia crepitans Back 2112px.jpg|Grey wings Image:Grey-winged Trumpeter.jpg|Another view of the bird's wings Image:Psophia crepitans.jpg|A group in French Guiana 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Grey-winged trumpeter」の詳細全文を読む スポンサード リンク
