They've been found from the mountainous regions of Nepal and in cities and towns in China, Vietnam, and Hong Kong.

It has been found in North America only one time in 2012; it was identified as a house swift after DNA sequencing.

House swifts build their nest using their saliva to messily stick together leaves, branches and feathers.

A fecal analysis discovered the house swift diet is almost solely from the arthropoda phylum.
