Feral city pigeons have a bad reputation but that says more about us humans than it says about the pigeon. It's also a relatively recent perception. Throughout history, pigeons have always been highly valued, both for their incredible skills to find their way home, as well as for their meat and the quality of their droppings. Before the use of artificial fertilizers, pigeon excrement was indispensable, especially in the Middle-east, for food production.
