Why The House Sparrows Are Unwelcome

The common house sparrow can be more than a nuisance: Its nesting habits can bring both disease and destruction

House sparrows (Passer domesticus (L.)), sometimes referred to as English sparrows, town sparrows or domestic sparrows, are probably the most citified and ubiquitous birds around human habitation and workplaces in the United States.

This bird is native to Eurasia and northern Africa, occurring from the United Kingdom east to Siberia (with the exception of Italy). The house sparrow has been introduced into many countries and is common in populated areas throughout the world. It even colonized the Falkland Islands by traveling there aboard a fleet of whalers from Uruguay.

Eight pairs of this non-native species were purposely imported from England to Brooklyn, N.Y., in 1850 (thus, its English sparrow moniker). The initial objective was to use this bird in a misguided attempt to control larvae of the linden moth. However, it was later discovered that house sparrows don’t feed on linden moth larvae.

Unwelcome Houseguest

House sparrows have since become a common pest bird that lives in close association with humans, greatly depending upon them for food and nesting sites. The birds are associated with the transmission of more than 25 diseases of humans and domestic animals, including St. Louis encephalitis.

About 75 species of ectoparasites have been reported from the house sparrow in Europe and North America. A number of these live in sparrow nests, from where they often enter structures and bite people and infest domestic animals (mites) or become stored product pests (dermestid beetles, clothes moths).

In addition, house sparrow feces deface and foul structures, park benches, outdoor lunch tables, statues and stair railings, and contaminate walkways around buildings. Their uric acid droppings can even damage automobile paint.

House sparrow nests often clog roof drains, plug gutters and downspouts, and cause roof leaks. Their bulky nests made of grass, straw, feathers, hair, weeds and other dried plant materials, strings and other miscellaneous flammable trash are serious fire hazards—especially when nests are located in electrical equipment, light fixtures, around power lines and electrical substations.

Bullying Behaviour

House sparrows are opportunistic, quarrelsome, aggressive, persistent, relentless and pugnacious competitors, and they’ll frequently out-compete, drive out and displace desirable native songbirds and other endemic species such as bluebirds, woodpeckers, robins, Carolina wrens and martins.

Bird houses that are placed out to accommodate songbirds are often usurped by house sparrows. In addition, these birds often consume and contaminate poultry and livestock feed at dairies and animal feed lots.

House sparrows are also opportunistic nesters: They’ll construct nests just about anywhere. They seldom build their nests in woods, thickets or fields like other sparrows do. In cities, the overwhelming majority of house sparrow nests are built in or on buildings. They prefer openings, cavities, holes, gaps and various construction defects that allow them access to an area.

Roof Risks

House sparrows are small birds, so to exclude them from constructing nests in structures, you must block entry holes 2 centimeters or larger. It’s a formidable task on two-story or taller structures, especially those with tile roofs.

On buildings with clay and concrete roof tiles, house sparrows commonly locate nests in areas under tiles at roof edges above fascia boards. When house sparrows shove nest materials under perimeter overhanging barrel tiles, they can dislodge these heavy, precariously hanging tiles and cause them to come crashing down.

In one case, a house sparrow nest (and the bird’s frequent comings and goings) dislodged a corner barrel tile that fell 30 feet to the concrete walkway below. It crashed with such force that it shattered.

The weight of the average concrete barrel tile is 12 pounds.: If this missile, falling from about 30 feet above, were to hit someone, it would certainly cause serious injury and possibly death.

In another case on the same structure, a second-story corner barrel tile was dislodged by a sparrow nest and its occupant’s accompanying activities. The tile fell onto a first-story roof, where it broke three concrete roof tiles before it cascaded down to a concrete walkway below and shattered. source

The sparrows cover a wide range of small brown birds which are difficult to identify.

1. White-throated Sparrow

White-throated sparrow - Wikipedia

They have a distinctive appearance with white throat markings and yellow lore. There are two adult variations referred to as white-striped and tan-striped forms. The white-striped ones have the black crown with white central stripes while the tan-striped on the other hand has a dark brown crown with tan-central stripe. These species try to pair with partners possessing opposite color morphology for breeding. White-striped birds are more aggressive in nature than the tan-striped ones when they are in their breeding phase. Song sparrows resemble tan-striped White-throated sparrows, but they are heavily streaked below without any yellow markings on the face. These creatures are famous for singing their pleasant chirp notes frequently, even during the winter season. They are found near the grounds mostly in woods, forest, and bushy areas.

2. House sparrow

They feed on millets, acorns and sunflower seeds along with small insects. They build their nests with coarse dried vegetation and then use the finer material like feathers, strings or paper for linings.

3. Chipping Sparrow

Chipping Sparrow | Audubon Field GuideIt is a fairly tame species with it’s widespread mostly found in North America. They are very pretty species with a splash of colors. Summer chipping sparrows are black with a bright rust crown while winter chipping sparrows are brown with dark upperparts. There is two subspecies Eastern and Western chipping sparrow. It is partial migrant flying towards South during winters and again towards North during spring. They sing loud, trilling songs most commonly in spring. Chipping sparrows may appear similar to American or Field sparrows, but you can identify them with a gray rump as it flies. They build their nest in a shrub or a tree, their nests, are flimsily constructed that light can easily pass through them. They feed on seeds of almost all varieties and protein-rich insects. Source
