FACT: Sparrows, starlings and pigeons do not make neat nests. They tend to be quite messy and can extend over several feet in a vent or chimney pipe. This poses a serious fire hazard. Birds will nest just about anywhere that can provide shelter, including roof vents, wall vents, chimneys, soffit and roofs.
FACT: Bird droppings are acidic and will eat into painted surfaces. They can cause permanent damage to building materials and automobiles if left unattended.
FACT: Nests in chimneys and vents can block the proper exhausting of carbon monoxide and moisture. This can cause carbon monoxide build-up and mould, both highly hazardous. Telltale visual signs of bird entry points are broken vents, bird droppings and protruding sticks and leaves.
FACT: The very young, very old and those with impaired immune systems are at greatest risk for severe illness from histoplasmosis. Mites, ticks and fleas are commonly found in birds’ nests. Inhaling bird feces can cause an incurable disease known as histoplasmosis, characterized by constant flu-like symptoms.
FACT: Most sparrows and starlings lay 6-7 eggs twice per year. Pigeons can lay 2-4 eggs all year round. One or two young usually die in the nest.
FACT: Sparrows can fit through an opening the size of a golf ball.
FACT: The most effective method to get rid of birds is to remove all the birds and nesting material and completely seal all potential entry points.
FACT: The bacteria and parasites in the nest as well as baby bird carcasses will cause severe odour and potential health problems.
Sparrows, starlings and pigeons are the most common bird species that come into conflict with people. Their nests and droppings can cause significant odour, damage and human health concerns.
