House sparrows are, unfortunately, one of the first birds people think of when they hear the word sparrow. This is because of the house sparrow's close association with urban areas and people. Unlike most of our native sparrows which live in many habitats outside city limits and feed on natural foods, the house sparrow relies upon man to provide its food. It feeds on waste grain and almost any other food that is thrown out as trash.

Control of this species is critical for the welfare of other cavity nesting birds such as wrens, bluebirds, tree swallows, chickadees and nuthatches. House sparrows will fiercely outcompete other species for nesting space, piercing eggs and killing fledglings and adult birds in the process.
