The ubiquitous "House Sparrow", the most abundant bird in North America, is descended from a few birds released in New York City's Central Park in the 1800's. They were imported from England to help control cankerworms in Brooklyn. Its scientific name, "domesticus" suggests this bird is intimately associated with man.
The female "House Sparrow" has a brown crown and is streaked brown above; her underparts are "dirty white" and she has a white eyebrow.
Courtship is a rough and tumble affair. The promiscuous female encourages fierce competition among the males.
Calls or song.
The "House Sparrow" sings a shrill and monotonous song of "cheep, cheerp, chirp" or "chirrup" throughout summer and winter.
Population and distribution.
The " House Sparrow" has become a bit of a pest. It steals food from other species, as well as outing martins and bluebirds from their homes and moving in.
The "House Sparrow" builds an untidy nest of any material it can find: grass, strips of paper, string and other debris, which is placed in either a natural or man-made cavity, such as window ledge, fire escape, etc. They will often roof this nest. In it she lays 5-6 white eggs, lightly speckled with brown. She has two or three broods a season.
