Their nests are usually modest, but well-built.

Four to six eggs are laid by female sparrows at a time. Reddish brown blotches appear on the eggs' white shells. Between eleven and fourteen days, they'll hatch. The young are taken care of by both, male and female parents. After hatching, the young are fed insects. Using their big feet, sparrows scrape seeds.
