The nesting materials are stuffed into holes of structures, often until the hole is almost full. Nesting materials may include dried vegetation, feathers, string, hair and grass. You will most likely see sparrow nests being built between February and May, using any materials the birds can find.

Such areas provide sparrows with easy access to food, shelter for nests. House sparrows are common in urban and suburban locations and prefer habitats associated with humans.
