Selective breeding has produced a wide variety of colors, patterns, and decorative feathers. Pigeons have been known to spread zoonoses, through ectoparasites and excrement they produce. Long-term reduction of feral pigeon populations can be achieved by restricting food supply, which in turn involves legislation and litter (garbage) control.
