Cinnamon-rumped Trogon

The cinnamon-rumped trogon is a trogon known for its colourful plumage. It is a close relative of the scarlet-rumped trogon, which also lives in the Malay Peninsula and Indonesia; the two look similar, but the cinnamon-rumped is slightly larger and the species can be told apart by the cinnamon rump that gives it its name (Wikipedia, general species account).
