Jamaican Doctorbird 2

The Doctor Bird (Trochilus polytmus) is the common name for the Swallow-Tail Hummingbird, the national bird of Jamaica. The feathers have a shimmering emerald green and black colour, a trait which is peculiar to this family of birds. The bird is able to fly backwards, this causes the feathers to make a humming sound when it flies (giving this avian family its common name of the hummingbird).
