Chamaetylas fuelleborni
The White-chested Alethe (*Chamaetylas fuelleborni*) is a strikingly inconspicuous member of the Old World flycatcher family (Muscicapidae), primarily inhabiting the dense understory of East African montane forests. Measuring 16-18 cm (6.3-7.1 inches) in length and weighing 25-35 grams, it presents a subtle yet distinctive appearance. Its dark greyish-olive to olive-brown upperparts contrast sharply with a brilliant white throat, breast, and belly, complemented by greyish flanks. This promine...
This species primarily inhabits subtropical and tropical moist montane forests, favoring dense undergrowth, ravines, and riverine areas. It is typically found at elevations ranging from 800 to 2600 meters.
Its diet consists primarily of insects (e.g., beetles, ants, termites, caterpillars), spiders, and other small invertebrates. It forages by hopping on the forest floor, gleaning and probing for prey in leaf litter and low vegetation.

It employs a distinctive ground-foraging strategy, hopping quietly on the forest floor, meticulously flicking leaves, probing moss, and gleaning in...
The White-chested Alethe is a resident species distributed across several disjunct montane forest blocks in East Africa, typically at elevations between 800 and 2600 meters. Four recognized subspecies account for its fragmented distribution. The nominate subspecies, *C. f. fuelleborni*, is found ...
