Sparrows in Bristol
Sparrows are one of the most commonly seen birds throughout the nation. These small brown and black birds have short tails and small but powerful beaks. Sparrows are especially attracted to man-made structures due to the amount of shelter and food available to them in larger buildings. Both sparrows and their droppings can carry pathogens that are harmful to humans. Tough, adaptable, and aggressive, sparrows can survive in city neighborhoods and in rural areas, where it may evict native birds from their nests. These birds build messy nests and are largely dependent on humans for both food resources and nesting sites.
House Sparrow Habitat
House sparrows are especially attracted to man-made structures because they usually offer numerous safe spaces to build nests with many potential food options. Nests are composed of twigs, grass, paper, and string, and are built-in gutters, vents, soffits, lamp poles, on rafters, building ledges, and almost any conceivable elevated, sheltered spot. Their nests are often hot spots for bugs and parasites that can make their way into buildings. Also, in some areas, sparrow nests can create fire hazards.
House Sparrow Behavior & Dangers
Sparrows love to stuff their nesting materials into tiny gaps – the perfect size is about 1 to 3 inches. This can include the framework of structures, letters of signs, corrugated overhangs, and even dryer vents. Around homes, gutters, and drainage pipes clogged with sparrow nests often back up, which can cause extensive water damage. Nests built in chimneys and ventilation systems can block airflow and spread diseases through the system.
Sparrows can crowd other birds at feeders and birdbaths, and as they aggressively defend their nests, they often push out other desirable songbird species, such as bluebirds. If you are dealing with sparrow problems in your Bristol property, always contact a bird removal specialist.
