According to the Ohio Department of Natural Resources Division of Wildlife, the male house sparrow has a gray body and crown, with a brown back and wings streaked with black. The female house sparrow is a dull brown with a pale eyebrow.
The house sparrow was first introduced to North America in the mid 1800s, so even though it is an invasive species, it has made a home without causing harm or damage to surrounding species and ecosystems.
Because they typically thrive around populated areas and typically eat insects and seeds, there are no prevention measures in place. The species has been established for more than a century and coexists with surrounding wildlife without causing significant damage.
