No, pigeons do not eat mice. Pigeons are primarily seed eaters and their diet mainly consists of grains, seeds, fruits, and vegetables.
While they are opportunistic feeders and may occasionally consume small insects or food scraps found in urban environments, they do not hunt or consume larger animals like mice. Their beaks and feeding habits are not suited for eating meat.
In urban areas, pigeons are often seen foraging in parks and streets, pecking at seeds and crumbs rather than seeking out other animals as food. Overall, their dietary preference is more aligned with plant-based materials rather than any form of animal protein.
