pest bird control sparrowThe House sparrow is the number two urban pest bird. Introduced as a species to North America, the sparrow quickly spread across the country due to its lack of natural enemies and its adaptive traits. Its ability to nest in urban structures, eat urban scraps and a large breeding capacity are some of these adaptive traits.

 

The House Sparrow is actually a member of the weaverbird family and not a true Sparrow. Weaverbirds create intricate nests and relative to their size, the largest nests in the bird world. Their legs and toes are favored for branch perching and their short conical bills are ideal for seed cracking. Their diet consists of seeds and grain, as well as fruits, vegetables, human table scraps and insects. They are boisterous, intelligent birds who roost in noisy flocks on branches of city trees, ivy covered walls and under eaves. Male House Sparrow have black throats and chest patches, light cheeks and brown nape. The female has a plain brownish chest and dull eye-stripe.

 

Sparrow Control / Removal

The most effective methods of control is REMOVAL, using Falconry, and capture netting installed in the flight paths by certified personnel to capture these birds in enclosed areas. Exclude sparrows from the area with 3/4" Exclusion Netting, making sure there are no gaps or crevices for the birds to pass through. The only ledge deterrent systems that are truly effective against sparrows are electrified ledge systems. New 2-chambered Sparrow Traps are quite effective at trapping small quantities of sparrows. The best trap has an elevated second chamber that keeps the birds happy and so content t hat they actually sing, attracting others to the trap. The trapping program should be combined with a nest removal program that will greatly reduce the population over time.

 

Sparrow Damage
House Sparrows are often a nuisance in manufacturing and food processing plants. Gutters and drainage pipes clogged with sparrow nests can backup and cause extensive water damage, and fires have been attributed to electrical shorts caused by machinery housing sparrow nests. Lastly, feces buildup can lead to structural damage from the uric acid in droppings, plus the bacteria, fungal agents and parasites in the feces also pose a health risk.
 

 

Sparrow Nesting 

They build large nests relative to size which function as the center of all activity. They prefer small enclosed places such as shutters, drainage piping, building rafters and corrugated metal siding. They will build a spherical nest in a tree or another exposed place if they have no other option. The building material will be sticks, with an inside lining of grass, string, fabrics or straw. The nest will often hold several families.Sparrow Breeding House sparrows only mate for a season. They average three broods per mating season with each brood containing four to seven eggs with an average of 20 offspring a year. Egg coloration will be white, pale blue or pale green with a few gray or brown dots. If unchecked, a breeding pair can grow to over 2,000 birds in two to three years.


Cycles
House Sparrows are not migratory, but in cold climates can show movement between rural/suburban breeding sites and warmer winter roosting sites in the city. House Sparrows are aggressive birds and will often force out other birds from their territories. They are flocking birds and will gather in the thousands to take over feeding and roosting areas.
