This bird, commonly found in Vanoise, has a black plumage, a grey head, and red tail and belly. A lively yet timid bird, it often shakes its tail twitchily. In the spring, the black redstart sings continually from the top of a roof or fence post. His song together with his posture and tail swing clearly indicate to the other males: “Private property, do not enter!”. Its song, punctuated by drier clicking sounds, is easily recognisable.
