Rusty-flanked Treecreeper
Certhia nipalensis
Well-marked treecreeper with a tiny bill, warm brown upperparts, and a dark brown ear patch on a white face. Warm rusty tones on the sides contrast sharply with a clean white throat and may meld into dark upperparts at a distance. Resembles Hodgson’s Treecreeper, but has a straighter- and shorter-billed profile and warm tones on the sides. Like other treecreepers, forages by scaling trees and branches, often in flocks with other species.

Other Birds
Bismarck Pitta
Erythropitta novaehibernicae
A long-legged, plump-bodied, mostly ground-dwelling bird with a bright red belly, dark blue wings, a greenish back, a bright red collar, a darker red crown, a light blue chest, and a brownish face. Resident in primary forest and forest edge habitats. Unique within its range. Voice is a low, trembling, raspy double-noted whistle, “croooo-eeeee.”
Forest Penduline-Tit
Anthoscopus flavifrons
Tiny, drab bird with a sharp bill, a dull olive-green back, and buffy yellow underparts and forehead. Found in lowland rainforest, secondary forest, and sometimes plantations, usually in the canopy. Uncommon and inconspicuous, in pairs or small flocks. Similar to Yellow Penduline-Tit, but much duller and found in different habitat. Could be confused with Tit-Hylia, but duller overall, without streaking on the head and breast. Could also be confused with some dull sunbirds, but has a shorter, deeper-based, and sharper bill. The vocalizations are very high-pitched “sit” notes that are easily missed.
Nicobar Sparrowhawk
Tachyspiza butleri
Small raptor with short wings. Male is gray above with thin brown barring on the pale underparts, and a black tail tip. Female is browner overall. Similar to Shikra, but Nicobar Sparrowhawk is smaller and paler, and has no tail bands. Known to be shy; sticks to treetops in forested habitats. Limited range restricted to a few of the Nicobar Islands.
