About the Bornean Stubtail
The Bornean stubtail 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 is long and buffish-brown, with an equally long dark grey eyestripe and a thin yellow eye-ring. Both sexes are similar.
