Besides scraps and fallen bird seeds, pigeons will also feed on seeds and fruits from trees, shrubs, and other urban vegetation. They may also frequent bird feeders and picnic areas where humans leave behind edible leftovers. Their varied diet also includes insects, spiders, and other small invertebrates that they can find in parks and gardens.
One concern related to pigeon feeding in cities is the spread of diseases. Pigeons can carry various pathogens and parasites that can be harmful to humans and other wildlife. It is therefore not advisable to feed pigeons and, instead, encourage them to forage naturally in urban environments.
