Birds can enter a home in the roof area or make nests in vents and other openings at the top of the roof. Starlings, sparrows, pigeons and other birds can enter a home or nest near the attic.The most common pest bird in the wildlife control industry is the pigeon. Pigeons are common in urban areas and live very well in conjunction with people. They often roost in public areas such as on building ledges, beams and store signs. Pigeons are also bred for meat, generally called squab and harvested from young birds. Pigeons grow to a very large size in the nest before they are fledged and able to fly and in this stage of their development (when they are called squabs) they are prized as food. They also frequently live in attics and we often deal with groups of pigeons living in the attics of homes, condos and apartment buildings.
