Description

EBird describes the bird as "A fairly small, localized bird of mid-elevation montane forest on Palawan. Medium-brown above and pale buffy below with heavy black streaks, especially on the chest. Note white throat, gray face, and pale rufous crown. Often found in mixed-species flocks. Somewhat similar to Pin-striped Tit-Babbler, but larger, with a white throat and a dark eye. Voice includes a downslurred nasal squeal and other varied calls." [2] This species does not exhibit sexual dimorphism.

It is the most distinctive among the four striped babblers (others being the Luzon striped babbler, the Panay striped babbler and the Negros striped babbler), which are generally plain brown versus the Palawan striped babbler's olive yellow markings. [3]

Ecology and behavior

The stomach contents of 2 individuals contained insects, seeds and some vegetable matter. Found singly, in pairs and small groups. Joins mixed-species feeding flocks that include Warbling white-eye, Mangrove whistler, Mountain leaf warbler and Palawan tit. Gleans dead leaves searching for food and forages in all levels of the cannopy.

Birds in breeding condition with enlarged gonads found in the months of April and May. Otherwise, no information on breeding, nest and fledgling stages. [4]

Habitat and conservation status

This species is known from primary montane mossy forest from 1,000 m to 2,000 m. It is only found on three mountains, namely Mount Mantalingajan, Mt. Victoria and Mt. Borangbato. [3]

Despite its extremely limited range, IUCN has assessed this bird as least concern but was formerly assessed as near-threatened. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range.The whole of Palawan was designated as a Biosphere Reserve; however, protection and enforcement of laws has been difficult and these threats still continue.
