Сейшельский шама Copsychus sechellarum

A large and distinctive magpie-robin of the granitic Seychelles islands. Black with a large white shoulder patch. In good light, the black plumage looks glossy purple or bluish. Found in woodland, gardens, and coastal forest. Formerly widespread, but now endangered and restricted to just a few islands. The song is a slow series of musical whistles; sometimes also includes harsher notes and imitations.
