Roosting is typically in cavities of large trees or on cliff faces where the stiff tail feathers aid grip.

The brown-backed needletail is a large, powerfully built swift famed for its blisteringly fast, direct flight. Needletails have stiff, spiny tail tips that help them brace against vertical surfaces when roosting. They spend almost all their time on the wing, often foraging high over ridges and forest canopies. Flocks frequently gather ahead of storms to exploit swarms of aerial insects.
