House sparrows are found in the most urban of habitats, living on food scraps, and nesting in building crevices--though they are still a common inhabitant of horse barns, farmyards and feedlots.
Seeds and grains will be on the house sparrow's normal menu throughout the year. In spring and summer they also eat insects.
