Description wikipedia

The Bornean stubtail (Urosphena whiteheadi) is a species of bird in the cettiid warbler family Cettiidae. It is endemic to the island of Borneo, where it inhabits forest floors and undergrowth in montane forests at elevations of 750–3,150 m (2,460–10,330 ft). It is a small, short-tailed warbler, measuring 9.5–10 cm (3.7–3.9 in) in length and having an average mass of 10.4 g (0.37 oz). The tops of the head and the upperparts are brown, with whitish underparts that turn grey at the sides of the breast and the flanks. The supercilium (stripe above the eye) is long and buffish-brown, with an equally long dark grey eyestripe (stripe through the eye) and a thin yellow eye-ring. Both sexes are similar. The species feeds on invertebrates, especially green aphids, foraging in a mouse-like manner on the ground and in undergrowth. Nests are made out of reddish plant fibres, with incubation taking 24 days on average. It is classified as being of least concern by the International Union for Conservation of Nature due to its sufficiently large range and stable population.
