The house swift (Apus nipalensis) is a species of swift in the family Apodidae. It is found in Japan, Nepal, and Southeast Asia. It is capable of flying long distances by alternately shutting off hemispheres of their brain in-flight. In May 2012, one was discovered in Ladner, British Columbia, the first known sighting in North America.
It was formerly considered a subspecies of the little swift.
