House Sparrow, F. C. Hennessey

F. C. Hennessey

About six inches long. Grayish brown, the back streaked with black. Brown wings with white bars. Buff white underside. Narrow white stripe over the eyes. White and chestnut cheek patches. White sides and neck. Black throat and breast.

An introduced species, it has prospered phenomenally, especially in conjunction with human habitation to the consternation people and other birds. 

Print a Free World Bird Calendar The English House Sparrow was imported to North America to protect trees from a caterpiller which is the larva of the Geometrid Moth.  Many disagreed with the wisdom of this move and even predicted they would become pests as they fed on seeds and buds, not insects.  Obviously, their words went unheeded.

Even after initial efforts failed, reintroduction was not only renewed, a seemingly concerted effort ensured its start (probably not actually concerted, but it might as well have been.)  Sparrows now thrive throughout most of the continent.

Eight pair were brought to the U.S. in 1850 for the purpose of ridding the shade trees of inch worms and in the spring of 1851 Nicholas Pike and other directors of the Brooklyn Institute released them in Brooklyn, New York.

They did not survive.  Nevertheless, destiny was on the side of the Hoard and Pike arranged for the importation of one hundred more which were released in 1852 and 1853.

In 1854 Colonel Rhodes imported and released some of the birds in Portland Maine and some in Quebec. In the next ten years, a few hundred more were imported and released in Quebec and the areas around Portland, Boston and New York.

In 1869, about one thousand were released in Philadelphia.  They were released in San Francisco, Cleveland, Cincinnati, St. Louis and several other cities in the interior.    Between 1874 and 1876 a few were released in Jackson and Owosso, Michigan and in 1881 they were introduced in Iowa.

It wasn't long before the destruction of crops, the spread of disease and parasites, competition with song birds, its filthy habits and a population explosion revealed its introduction as a huge mistake.

The Ivory Bill Publishes Wildlife & Habitat Conservation News, Government Management Activities, and Opportunities for Public Input But control and extermination attempts with bounties and poison have proved useless against such a pervasive species. The winged rat is in complete possession of the continent.  It does considerable damage to grain crops and storage. The sparrow's movements between farms expedites the spread of chicken lice and mites and livestock diseases which can be spread by mere physical contact.

A few House Sparrows can multiply into thousands in a few years because they regularly raise three and sometimes as many as five broods per year, each brood averaging around five or six birds.

It builds nests in almost any nook or cranny in farms, towns and cities. The droppings from large flocks roosting on houses and other buildings despoil window trim, porches and ornamental work. It eats buds, young sprouts, flowers and seeds of almost anything.

It is a persistent adversary of many birds, especially those that seek shelter in bird houses or nest near humans including Bluebirds, Wrens, Phoebes, Tree Swallows, Purple Martins, Song Sparrows, Chickadees, Flycatchers Thrushes, Tanagers, Robins and more.

Since it is a year around resident it has a head start in the spring, invading the bird houses we place for migrating song birds. It dominates feeders intended for song birds leaving most of the seed on the ground uneaten.

House Sparrow, Louis Agassiz Fuertes

Monitor bird houses with entrance holes larger than 1 3/8" diameter if you don't want house sparrows.  That being the reason my favorite bird house, the Side Mount, has an entrance hole of 1 3/8" diameter.   Actually, 3/8" is marginal and some report that small sparrows may fit.

The Side Mount box might attract Wrens, Chickadees, Nuthatches, Titmice, Downy Woodpeckers and Tree Swallows.
