White-rumped Swiftlet

Aerodramus nuditarsus

The White-rumped Swiftlet is a small, insectivorous bird found in Southeast Asia. It has a dark brown body with a distinctive white rump, and its wings are long and narrow, enabling rapid and agile flight. These swiftlets are highly gregarious, forming large colonies in caves and cliffs where they build their cup-shaped nests using saliva. They are known for their remarkable echolocation abilities, using high-pitched calls to navigate and locate prey in the air. The species plays a vital role in controlling insect populations and is an important component of the ecosystem in its range.
