The presence of pigeons at a water source intended for smaller birds can present several problems. These larger birds may dominate the space, preventing smaller species from accessing the water. Their droppings can also contaminate the water, posing a health risk to all birds using the birdbath and requiring more frequent cleaning.
Maintaining a clean and accessible water source benefits the local ecosystem. Smaller bird species rely on birdbaths for hydration and preening, particularly in urban environments where natural water sources are scarce. Discouraging pigeons promotes a healthier and more diverse bird population in the area.
