The grey-rumped treeswift (''Hemiprocne longipennis'') is a species of bird in the Hemiprocnidae family. There are currently four extant species in the family. Like the other members of Hemiprocnidae, this species is closely related to true swifts as well. However, unlike true swifts, the treeswifts are arboreal in nature, often seen perched on trees, high tension power transmission lines and on pylons. When perched, the wing tips cross over the tail. This species is commonly found in peninsular Malaysia but has an extremely large range with limited information about the population trend,.〔〔Jeyarajasingam. A. and Pearson. A. 2012. A Field Guide to the Birds of Peninsular Malaysia and Singapore. Oxford University press〕 ==Description== Adult male with a distinct dark grey throat and chest contrasting with a white belly.Ear coverts are dull orange red/chestnut colored. Adult female lacks the dull orange red/chestnut coloration on the ear coverts. When perched the wing tips cross over across the tail. Both sexes have a greenish sheen to the upper parts.〔
