The familiar House Sparrow is a chunky sparrow with a large head and short tail. It was introduced to this country from Europe and is in a different family from our native sparrows. Males in breeding plumage have streaked chestnut backs, chestnut heads, and gray crowns. They have black throats and breasts and light gray cheeks and underparts. Males in non-breeding plumage look similar, but lack the black throat and breast, have less distinct markings on their heads, and have yellowish rather than black bills. Females have drab, grayish-brown, unstreaked breasts, with mottled buff and brown upperparts and light eye-stripes.
