Why are pigeons such filthy animals?
<|assistant|>
Pigeons are filthy animals primarily due to the fact that they lack tidiness in their nesting and are constantly exposed to human environments. They also lack the grooming and preening behaviors that keep other birds in control of their body odor, feathers and overall physical presentation. They also have a fondness for human food waste, garbage and other easy sources of nutrition, often creating an unsanitary mess around feeding and nesting areas. Pigeon feces often carry diseases that can spread to people and other animals.
