[6] Rothschild's swift is found from Bolivia's Santa Cruz Department south into northwestern Argentina as far as Córdoba Province.

[6] Rothschild's swift appears to be a year-round resident in most of its range, though it might winter at the northern end of it.

[6] Like all swifts, Rothschild's is an aerial insectivore, but no details of its diet are known.

As of late 2022, xeno-canto had a single recording of a Rothschild's swift vocalization, and the Cornell Lab of Ornithology's Macaulay Library had none.

It has a small range and an estimated population of 6000 to 15,000 mature individuals; the latter is believed to be stable.
