The dark-fronted babbler (Dumetia atriceps) is an Old World babbler found in the Western Ghats of India and the forests of Sri Lanka. They are small chestnut brown birds with a dark black cap, a whitish underside and pale yellow iris. They forage in flocks in the undergrowth of forests constantly making calls and uttering alarm calls when disturbed.

Taxonomy

The dark-fronted babbler was formally described in 1839 by the English naturalist Thomas Jerdon under the binomial name Brachypteryx atriceps. He specified the range as Thrissur, Wadakkancherry, Coonoor and the Wayanad of southwest India. The type locality was restricted to Wayanad by Hugh Whistler in 1935. The dark-fronted babbler was formerly placed in the monotypic genus Rhopocichla. It was moved to Dumetia with the tawny-bellied babbler based on the results of a large molecular phylogenetic study published in 2019. The genus Dumetia was introduced in 1852 by the English zoologist Edward Blyth. The genus name is from Latin dumetum, dumeti meaning "thicket". The specific epithet atriceps combines the Latin ater meaning "black" with -ceps meaning "-capped" or "-headed".

Four subspecies are recognised: and the upper parts are more olive. The nominate form found north of the Palghat Gap has the hood dark black. In Sri Lanka, the subspecies siccata is found in the lower elevation while nigrifrons is found in the wet zone. The former has more olive on the upperparts while the later is rufescent on the upperparts.

Behaviour and ecology

Babblers have a weak flight and are residents within their range. They forage in parties and clamber up vegetation and when disturbed, they tend to drop from the topmost perches of the bush into the undergrowth. Their typical habitat is undergrowth in forest or on the edge of forests in more open growth. They often join mixed-species foraging flocks.

The breeding season is May to July. This babbler builds its nest low down in a bush, the nest being a ball of leaves, often of bamboo. The nest looks like some dry leaves stuck in a bush with the opening on the side. The normal clutch is two eggs. They are also said to construct dormitory nests within which birds may sometimes roost. These dormitory nests are not lined.
