The Imperial Amazon is the largest, and probably the most spectacular, species in the genus Amazona . The nape, back and upper tail covert feathers are deep green with a faint black edge.
Wings are also green, with red, maroon and blue feathers throughout.
The undersides of flight feathers are green, the tail dull reddish-brown tipped with blue. The Imperial has a greyish bill, yellow to orange iris and grey legs. Juvenile birds of this species have yet to be described. The Sisserou is Dominica's national symbol, yet fewer than 200 of these shy, beautiful birds remain in the wild. It is found only in the northern region of the island, along the slopes of the Caribbean's largest volcano, Morne Diablotin.
