The eastern black-headed batis (Batis minor) is a passerine bird in the family Platysteiridae from eastern Africa. It was formerly treated as conspecific with the western black-headed batis. The eastern black-headed batis was described by the German ornithologist Carlo von Erlanger in 1901 who considered the taxon as a subspecies of the grey-headed batis (Batis orientalis) and introduced the trinomial name Batis orientalis minor.
Two subspecies are recognised: It is a small, stocky, rather restless, flycatcher like bird with a white, black and grey plumage. The forehead, crown and nape are blackish grey with a white supercilium and loral spot, the mask is glossy bluish black and there is a white spot on the nape. The mantle and back are dark grey with a paler rump, females have a greyer mantle. The underparts are white with a glossy black breast band, which is dark reddish brown in the females. The tail is black with white outer tail feathers... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Eastern Black-headed Batis is recorded against all the birds logged in Dar es-Salaam (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
