The Eastern black-headed batis, a diminutive and stocky bird, presents a striking appearance with its contrasting plumage. The species measures a mere 10 cm in length and tips the scales at a lightweight 9.3–13.8 g. Its plumage is a mosaic of white, black, and grey. The bird's head is adorned with a blackish-grey crown, complemented by a white supercilium and loral spot. A glossy bluish-black mask and a distinctive white nape spot further accentuate its head. The mantle and back are cloaked in dark grey, transitioning to a paler rump, while the underparts are a pristine white, bisected by a glossy black breast band. Females exhibit a greyer mantle and a dark reddish-brown breast band. The tail is predominantly black with white outer feathers, and the wings are black with a white stripe. The bill and legs are a deep black, and the eyes are a vivid yellow. Juvenile birds resemble females but have a browner hue.
When identifying the Eastern black-headed batis, look for the distinctive head pattern with its blackish-grey crown and white supercilium. The glossy black breast band on a white underpart is a key feature, along with the black and white wing pattern. The bird's small size and restless behavior are also indicative.
This species is adaptable and can be found in a range of environments, provided that trees are available. Habitats include arid savannah woodlands, the fringes of montane evergreen forests with juniper, and even human-altered landscapes such as parks and gardens.
The Eastern black-headed batis graces the eastern regions of Africa with its presence. It is known to inhabit southern Somalia, southeastern Kenya, and eastern Tanzania.
The Eastern black-headed batis is known to live in pairs or small family groups. Its behavior is consistent with that of other batises, characterized by a seemingly restless disposition.
Insects form the staple of this bird's diet. It employs a foraging strategy that includes searching through foliage and engaging in flycatching to secure its meals.
The Eastern black-headed batis is currently classified as Least Concern by the IUCN, indicating that, for now, the species does not face an immediate threat of extinction.
