The English Sparrow
is a Old World weaver finch originally native the the Mediterranean
region. The first English Sparrows were purposely introduced to New
York City during the nineteenth century, in an attempt to control pests.
The current population is descended from 100 birds.
DAMAGE AND CONCERN
Almost all native
cavity-nesting species are vulnerable to the aggressive English Sparrow.
An estimated 20 percent of all martin nest boxes are occupied by House
Sparrows.
CONTROL
Some nest box
designs are less popular with this species. Nest boxes that are closer
to farmyards, houses, outbuildings, feedlots, or barns are more likely
to attract English Sparrows. Use only sunflower or safflower seeds to
feed birds. Sparrows prefer millet, cracked corn, and wheat.
