The English Sparrow





The first English sparrow was brought to the United States in 1850, but

it was not until 1870 that the species can be said to have firmly

established itself. Since then it has taken possession of the country.

Its fecundity is amazing. In the latitude of New York and southward it

hatches, as a rule, five or six broods in a season, with from four to

six young in a brood. Assuming the average annual product of a pair to

be twenty-four young, of which half are females and half males, and

assuming further, for the sake of computation, that all live, together

with their offspring, it will be seen that in ten years the progeny of a

single pair would be 275,716,983,698.
