Across the Great Plains are legions of abandoned granaries, many still in quite good repair. In them, by their own choosing, nest the feral pigeons, descendants of domestic birds brought to this continent hundreds of years ago, which in turn are the descendants of the wild ancestral rock dove, a denizen of remote sea coast cliff fastnesses. Were an enterprising person to outfit these bins with working doors and simple barred entranceways of a size to admit pigeons but exclude their main predators, the Great-horned owls, here would be a ready source of emergency food for the plains-dweller, a variation on the urban "food forest."
Pigeons and doves (which are two different words for the same group of birds,) are the only birds that dip their beaks into their water source and simply suck the water up, like a mammal - all others must "dip and tip" their heads. They are even easier to care for than chickens, being incredibly hardy (they often begin nesting in February, even in our climate, without any artificial heat source) willing and capable of caring entirely for themselves provided there is a source of forage on the land. And giving back almost as much as chickens and on some levels more. Perhaps if you are an urbanite frustrated by laws limiting your keeping of chickens, you should look into the legality of establishing a pigeon loft!
Or better yet, keep both.
