Like the other members of the Hemiprocnidae, this species is closely related to true swifts, but unlike true swifts, the treeswifts are arboreal in nature, often seen perched on trees and high-tension power transmission lines, and on pylons.

This species is commonly found in peninsular Malaysia, but has an extremely large range with limited information about the population trend,.

[1][2] Adult males have a distinct dark grey throat and chest contrasting with a white belly.

The half-saucer-shaped nest is made from hardened saliva interspersed with feathers, mosses, and/or flakes of tree bark.

[3] Similarly, the parent birds reportedly brooded by perching on the branch above the nest and fluffing their breast feathers out to cover it.
