Origma robusta
The Mountain Mouse-warbler (Origma robusta) is a compact and sturdily built passerine, measuring approximately 12-14 cm in length and weighing 15-20 grams. Its cryptic plumage features dull olive-brown to grey-brown upperparts, often with subtle streaking, while its underparts are a paler greyish-buff, transitioning to a buffy-white throat.

Endemic to subalpine and montane eucalypt forests, wet sclerophyll forests, and rocky outcrops with dense undergrowth. Primarily found at elevations ranging from 800 to 1800 meters.
Primarily insectivorous, feeding on a diverse array of small invertebrates including beetles, spiders, and caterpillars. Forages mainly by gleaning from the ground, leaf litter, and low-lying vegetation.

It moves with a characteristic mouse-like scurry, navigating dense vegetation with remarkable agility, and roosts in she...
