Black-throated Bushtit

The black-throated bushtit, scientifically known as Aegithalos concinnus, is a diminutive passerine bird belonging to the Aegithalidae family. This charming avian species is characterized by its relatively short tail, contrasting with the elongated tail of its cousin, the long-tailed tit. Both male and female black-throated bushtits share a similar appearance, featuring a distinctive black 'bandit mask' around their eyes and a black throat. The plumage varies among subspecies, with the nominate race donning a chestnut cap, breast band, and flanks, a white belly, and a dark grey back, wings, and tail. Other subspecies may exhibit grey caps or entirely grey bellies and flanks, but lack the chest band.

Identification Tips

When attempting to identify the black-throated bushtit, look for its black throat and eye mask, which are key distinguishing features. The bird's size is also a clue, as it measures approximately 10.5 cm in length and weighs between 4-9 grams. Plumage variations can help determine the specific subspecies, with some having chestnut accents and others displaying more grey.

Habitat

The black-throated bushtit is found in open broadleaf forests and pine forests, preferring middle altitudes for its habitat. These environments provide the necessary cover and food sources for the species to thrive.

Distribution

This species has a wide range across Asia, from the Himalayan foothills through northern India, northeastern Bangladesh, Nepal, Bhutan, northern Myanmar, Vietnam, and Taiwan. There are also isolated populations in southern Vietnam, Hainan Island, and northern China up to the Yellow River.

Behaviour

The black-throated bushtit is a highly sociable bird, often seen in large flocks that can number up to 40 individuals. These flocks are a bustling community, flitting through the forest in search of sustenance and companionship.

Breeding

During the breeding season, these birds exhibit remarkable architectural skills, constructing exquisite nests from moss and lichen. These nests dangle elegantly from tree branches, providing a secure cradle for their young.

Feeding

The diet of the black-throated bushtit is varied, including small insects and spiders, as well as seeds, fruits, and berries, with a particular fondness for raspberries. Their feeding groups tend to expand in size outside of the breeding season, and they are known to participate in mixed-species foraging flocks.

Conservation status

The black-throated bushtit is currently listed as Least Concern on the IUCN Red List, indicating that, for now, this species is not at immediate risk of decline. However, continued monitoring is essential to ensure its ongoing survival.
