The adult male House Sparrow is quite distinctive but might be confused with the very local Eurasian Tree Sparrow (St. Louis, Missouri). The Eurasian Tree Sparrow has a black spot on the ear coverts and an entirely brown crown. The female House Sparrow looks somewhat similar to a number of species of sparrows but has unstreaked underparts, tawny streaks on the back, and a large yellowish bill. The female Dickcissel also has a large bill but it is gray, not yellow, and usually has some yellow in the face and a rusty patch in the wing.
