Pigeons were a type of bird commonly found in urban areas.
The Pigeon Lady often fed birdseed to many pigeons at a time in Central Park and used them against Harry Lyme and Marv Murchins when they tried to murder Kevin McCallister. After distracting the burglars to rescue Kevin, she covered them in a bucketful of birdseed, which attracted a horde of pigeons that pinned the Sticky Bandits down until four police officers arrived and arrested them.
