General Description: House Sparrows (Passer domesticus) are small, sexually dimorphic, sparrow-like birds with heavy bills. The males are brown with a bold black bib, and the females are overall brown with a bold, light eyeline. During winter, the bold marks fade, but remain present. The bill is large.

Taxonomy: Passeriformes, Passeridae.

Favored Habitat: Most common in fast-food parking lots, these birds can be found in urban parks and yards, especially around seed feeders.

Where to Find: Urban areas with food scraps.

Comments: House Sparrows are not native to North America; they were introduced from Europe. Similar to other non-native species, House Sparrows probably affect native species adversely, but they primarily fill the niche of cleaning up food scraps around fast-food restaurants.
