Dark-necked Tailorbird

The dark-necked tailorbird is a tiny, long-billed songbird, about 10.5–12 centimetres long, with olive upperparts, a rufous crown and greyish underparts. The male's blackish streak or patch on the upper breast may be partly concealed, while the yellow vent helps separate it from Common Tailorbird. It usually stays low and hidden in vegetation, where paired birds may exchange trilled phrases in a conspicuous duet (Birds of Singapore; Singapore NParks).

Its range extends from Bangladesh through southern China and mainland Southeast Asia, including Vietnam. It occupies forest undergrowth, secondary growth, scrub, degraded woodland, parks and gardens, and is commonly detected in bushes rather than an open canopy. The bird searches leaves and tangled stems for small invertebrates such as spiders, caterpillars, beetles, aphids and flies. Like other tailorbirds, it constructs a concealed nest associated with living leaves (Singapore NParks; BirdsandMe, general species account).
