Description
The male has a blue head, mantle, back, wings and upper parts of the breast contrasting with an orange lower part of the breast and the belly. The female has a brown back, wings and tail and pale underparts, mottled and streaked with bold brown markings. In both sexes, the base of the outer tail feathers is orange. Males can often be detected by their song - "toee toee toee" issuing from the lower parts of the tree canopy.
Distribution and habitat
This species is endemic to Madagascar and is found in the tropical forests. In the north of the island it is usually found in mid- and high-altitude rainforests, in forest fringes and adjacent scrubby areas. In the south it inhabits dry forests and semi-arid rocky areas. It appears to be able to recolonise burnt areas when the flora regrows.
