Sparrows can prove ruinous to crops, but they’re particularly disastrous if they invade your buildings and other infrastructure. Sparrows like to build large, dense nests made of grass, straw, weeds, and garbage. These nests can do damage to the sidings of houses, and clog drainage pipes and gutters.
To spot a sparrow, look out for a black chest and white cheeks in males, and a grey color in females. They also have a noisy, droning chirp that is easy to distinguish.
