House Sparrow (Passer domesticus)
The house sparrow is one of the introduced species that has succeeded greatly in North America. The species is native to Britain, northern Scandinavia, and northern Siberia to northern Africa, Arabia, India, and Burma.
The number of house sparrows in North America is estimated at approximately 150,000,000 birds, but the Breeding Bird Survey data indicates that the population is declining. House sparrows are common throughout the Mississippi National River and Recreation Area, with most being found around areas of human activity, such as farms and cities.
This invasive species vigorously competes with our native bluebirds for nesting cavities and will destroy eggs and nests of these more desirable birds.
