Rwenzori batis

The Rwenzori batis (Batis diops) is a bird native to the Albertine Rift montane forests, where it inhabits altitudes of 1,340–3,300 m (4,400–10,830 ft).

The Rwenzori batis is a small, active black and white Old World flycatcher. The upperparts are dark bluish black with a white stripe along the wing and a white loral spot. The underparts are mostly white except for a glossy bluish black breast band, a black chin spot and black thighs and grey axillaries. The tail is black with the feathers having white tips and white edges on the outer tail feathers. The sexes are similar except that males have yellow eyes and females have been reported sometimes to have orangey-red eyes. Juveniles are similar to adults but the plumage has a more rufous cast. The Rwenzori batis measures 11–12 cm (4.3–4.7 in) in length, and it weighs 8–15.5 g (0.28–0.55 oz).

The territorial call is a slow low-pitched whistle, which has been described as both ventriloqual and eerie. It is repeated with an interval of 2–4 seconds between each whistle.
