Grey-rumped Swiftlet

Collocalia uropygialis

The Grey-rumped Swiftlet is a small, insectivorous bird found in Southeast Asia. It has a distinctive grey-brown plumage with a slightly paler rump, and a short, forked tail. These swiftlets are known for their aerial acrobatics, often seen darting and swooping through the sky as they hunt for flying insects. They nest in caves and cliffs, using their saliva to construct their nests. They are highly social birds, often forming large flocks. The species is important in maintaining insect populations and is a valuable part of the ecosystem.
