House Sparrows


Extremely common throughout the world, sparrows live in close proximity to humans. House sparrows are not native to North America, and their presence adds to the decline of native bird populations. Sparrows regularly take up residence in and around manmade buildings, which contributes to noise pollution as well as various health hazards that result from their droppings.
Birds in the bathroom fan or kitchen vent? Sparrows making nests in your attic or garage? Those little weaver finches in the attic may well be sparrows. Sometimes sparrows cause damage by pecking at insulation inside attics. The nests of sparrows can also be dangerous, as they can be potential fire hazards.

Biology & Behavior

House sparrows, also known as English sparrows, are established throughout North America. Nest building begins as early as April, with both sexes taking part in the activity. Nests may be located almost anywhere. Three to seven eggs are laid, commonly 5, and 2 or 3 broods are raised each year. Soon after the young leave the nest, they gather in small flocks. As the summer advances, adults join the juveniles until the flock may number several hundred.



Damage from house sparrows includes loss of grain in fields, animal feed stations, storage sheds, and feed lots, and deprivation on sprouting vegetables and flower crops, seeds of newly seeded lawns, fruit tree and ornamental buds, and pecking of ripening fruit. ​The house sparrow harbors the chicken louse and bird louse. House sparrows are capable of transmitting foul cholera, turkey blackhead, Newcastle disease, avian tuberculosis, Eastern equine encephalitis, pullorum, canary pox, anthrax, and numerous hellminths, fungal and protozoan parasites. The noise and filth associated with their nests are nuisances in urban areas.
