Black-throated Bushtit

Overview

The black-throated bushtit (Aegithalos concinnus) is a very small passerine bird belonging to the family Aegithalidae. Although currently assessed as Least Concern, genetic studies suggest its six recognised subspecies may represent separate species.

Identification

• Around 10.5 cm long and weighing 4–9 g, with a medium-length tail in contrast to the related long-tailed tit.
• Distinctive black throat and a black 'bandit mask' around the eye.
• Plumage varies by subspecies, featuring a chestnut cap, breast band, and flanks with a dark grey back, wings, and tail, or alternatively all-grey bellies and flanks.
• Both sexes appear alike.

Habitat

This species inhabits open broadleaf and pine forests, generally occurring at middle altitudes. Its range extends from the foothills of the Himalayas across northern India, north-eastern Bangladesh, Nepal, Bhutan, northern Myanmar, Vietnam, and Taiwan, with disjunct populations in southern Vietnam, eastern Cambodia, Hainan, and northern China up to the Yellow River.

Diet

The black-throated bushtit feeds on small insects and spiders, as well as small seeds, fruits, and berries, particularly raspberries. It forages in social groups that often join mixed-species feeding flocks.

Highly social, these birds travel in large flocks of up to 40 individuals, with group numbers swelling further during the non-breeding season. Their nests are uniquely constructed from moss and lichen, hanging from tree branches.
