Why are pigeons such filthy animals?
<|assistant|>
Pigeons can be filthy animals for a number of reasons. Firstly, because they are always squatting in areas where they defecate and nest, their nests and feces attract vermin, flies, and other animals. This encourages bacterial growth, making the area even more unsanitary. Also, since pigeons are not particularly careful about where they are roosting, they will often rest and preen in areas with humans, spreading diseases like salmonella and mites. Finally, since pigeons are not particularly fastidious about consuming and ingesting nutrients, their food can contain germs and bacteria, which also contributes to their overall filthiness.
