Black bill
White eye ring, dark eye
Adult Female
The female bird is much duller, however her dark bill, dark eye, light eye ring and rust red tail still make her quite distinctive. Her plain pale buff breast and underside differentiate her from a winter male who always has a strong tinge of orange. She differs from the mousy grey of the female Black Redstart by being much browner.
Juvenile male Redstart
Juvenile
Juvenile male birds have a white fringe to the black on the face and neck, they also have a white 'v' on the forehead. Juvenile female birds look much like the adult but a little paler and a close examination reveals small crescent shaped markings on the breast.
