Collocalia affinis
The Plume-toed Swiftlet (Collocalia affinis) is a small, agile aerial insectivore, typically measuring 9-11 cm in length with a wingspan of approximately 20-22 cm. Its plumage is predominantly sooty blackish-brown, often appearing uniformly dark in flight, though some individuals may show a slightly paler, indistinct rump. A key diagnostic feature, though virtually impossible to observe in the field, is the presence of small feather tufts or "plumes" at the base of its toes, giving the specie...
Primarily found in open country, over forests, coastal areas, and near human settlements, typically ranging from lowlands up to elevations of around 1,500-2,000 meters.
Exclusively insectivorous, feeding on a wide variety of small, flying insects, which it captures on the wing through aerial hawking.
Plume-toed Swiftlets are highly diurnal, spending nearly their entire day continuously airborne, foraging for insects. They are highly social birds, often observed in large, swirling flocks, particularly at prime foraging locations or when returning to communal roosts. Roosting occurs communally ...
The Plume-toed Swiftlet boasts a widespread distribution across Southeast Asia and parts of the Indian subcontinent, encompassing a largely resident, non-migratory population. Its breeding and year-round range extends from Northeast India, Bangladesh, and Myanmar, through Thailand, Peninsular Mal...
Least Concern
- The "plumes" on its toes are microscopic and difficult to observe in the field, making it a challenge for birders to confirm this diagnostic feature. - Unlike some of its swiftlet relatives, the Plume-toed Swiftlet does not build the famous "edible bird's nests" that are prized in some Asian cu...
