Pale-billed Scrubwren

Aethomyias spilodera

The Pale-billed Scrubwren, *Aethomyias spilodera*, is a charmingly cryptic passerine endemic to the montane rainforests of New Guinea, typically measuring around 12-14 cm in length and weighing 10-15 grams. Its plumage is generally olive-brown on the upperparts, contrasting with paler, often creamy-white underparts and streaky flanks, providing excellent camouflage within its dense understory habitat. The most distinctive field mark is its unique pale bill, which can range from pinkish to whi...

Habitat

This scrubwren primarily inhabits tropical and subtropical moist montane forests, including secondary growth and forest edges, typically at elevations ranging from 1,000 to 2,800 meters above sea level.

Diet

The diet of the Pale-billed Scrubwren consists predominantly of small insects, spiders, and other minute invertebrates, which it gleans from foliage, bark, and occasionally the forest floor.

Pale-billed Scrubwrens are diurnal and highly active, spending their days foraging in the dense undergrowth and lower to mid-story vegetation. They employ a 'gleaning' foraging strategy, meticulously searching leaves, twigs, and bark for small invertebrates, often moving with quick, jerky movemen...
