What is the impact of feral pigeons?

Feral pigeons can have several ecological and urban impacts. They can contribute to the spread of diseases that may affect humans and other animals, as well as cause property damage through their droppings, which can corrode buildings and vehicles. Additionally, their large populations can disrupt local ecosystems by outcompeting native bird species for resources. In urban areas, they may also be considered a nuisance, leading to conflicts with residents and city management efforts.
