Hemiprocne longipennis,
Grey-rumped Treeswift |
The treeswifts form a small family, Hemiprocnidae in the Apodiformes
order which includ es
three families: treeswifts, swifts and (maybe a bit surprisingly)
hummingbirds. Hemiprocnidae is only in the Oriental region and only has
one genus with four species. Treeswifts differ from true swift in that
they can and often do perch on branches, they are arboreal birds
The Grey-rumped Treeswift forms a superspecies and was previously
considered conspicific with the Crested Treeswift (H. coronata). The
former occurs in the Sunda subregion plus Sulawesi, the latter replaces
it in Thailand and Indochina into India. Incredibly, for these
widespread and fairly numerous two species there are big gaps in our
knowledge of their nesting biology, neither incubation nor fledging
periods have ever been recorded.
