The grey-rumped treeswift (Hemiprocne longipennis) is a species of bird in the Hemiprocnidae family. Currently, four extant species are placed in the family. Like the other members of the Hemiprocnidae, this species is closely related to true swifts, but unlike true swifts, the treeswifts are arboreal, often seen perched on trees, high-tension power transmission lines, and pylons. When perched, the wing tips cross over the tail. This species is commonly found in peninsular Malaysia, but has an extremely large range; there is limited information about population trends.

Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
