They forage aggressively for food on the ground, hopping whenever they do not fly. Flight is direct, with continued wing-flapping and no gliding involved. Despite their small size, they will often threaten or attack other birds, and will inhabit a relatively small area in decently sized flocks. Sparrows are also big eagers. They favor a variety of seeds, supplemented occasionally by insects and bird feeders.
They have their offspring between February and May, and build their nests in building crevices and on or around nearby trees. They will usually lay up to 8 eggs, and their incubation period lasts as long as 2 weeks. Sparrows will fly around collecting food, and will feed their young through regurgitation.
There are several methods you can use to help control your sparrow population. Netting is the best method of reducing bird roosting, nesting, and feeding. It isn’t subject to bird acclimation, is economically feasible, and neighbours love nets compared to the other bird scaring methods. Spike strips and wires are also popular methods to prevent birds from roosting on ledges. These are relatively inexpensive and not difficult to install. However, if not properly located, will usually be useless.
