The crimson sunbird is a species belonging to the family of sunbirds. It is a resident breeder in tropical South East Asia and Indonesia. The male is easily recognized by its red head and neck, while the female is a more unimpressive olive color. It can reach a size between 11 and 13.5 centimeters. The bill, the upper part of the head and the wings are black. Sunbirds have the ability to hover like a hummingbird, but they also like to perch while foraging.
The crimson sunbird is the unofficial national bird of Singapore.
