Across the old Roman Empire were scattered examples of the columbarium after the genus name of the Rock dove, Columba - "culvery" to the Cornish, "doocot" to the Scottish, "dovecote" to the English. These structures, some quite elegant, were all over Europe (at one time England boasted over 26,000 dovecotes.) They were the homes of pigeons. Most of these dovecotes were designed to hold between 200 and 500 pairs. They varied in design, but were in essence a brick or stone shed, stable or barn with portholes of a size to admit pigeons but not their predators, nesting ledges inside, and a door to admit humans. Some were rumored to have held up to 5,000 birds, and when the Roman Legions marched, these dovecotes provided a ready and self-sustaining source of food in the way of squab - a delicacy to this day. This was a brilliant and elegant system, a farm that farmed itself. Each day the pigeons would leave their cotes, scouring the countryside for seeds and waste grain. Interference with the birds was prohibited.
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 redundant "food forest" concept of today. (Of course there’s food in the forest, people up until very recently would have responded, scratching their heads. Always has been.)
Pigeons have lived alongside man for thousands of years, with the first images of them being found by archaeologists in Mesopotamia (modern Iraq) and dating back to 3000 BC. It was the Sumerians in Mesopotamia that first started to breed white doves from the wild pigeon that we see in our towns and cities today, and this undoubtedly accounts for the amazing variety of colors that are found in the average flock of urban pigeons. (And if you think they're dirty, you're looking far too closely at the bird as opposed to the city, ourselves.) To ancient peoples, a white pigeon would have seemed miraculous and this explains why the bird was widely worshipped and considered to be sacred. Throughout human history the pigeon has adopted many roles ranging from symbols of gods and goddesses through to sacrificial victims, messengers, pets, food and even war heroes!
Miraculous they are. We keep a loft of sorts at our place. Natural selection of the flock, begun with a handful of white and ‘red’-winged birds two decades ago, is allowed to play out, siginificantly. We feed and water the birds which come and go as they please, risking the plentiful goshawks and ravens here that weed out all but the strongest fliers, which then go on to breed. When I look at these birds up close, I am always struck by their marvelous beauty. Everything about them is perfect, sleek and sublime, nothing extreme. They are to me, the "a-priori bird," the bird that could be used as an example of "best in design" or the apogee of “bird” that appears in the mind’s eye. But looking at them as they interact in the loft is only the beginning of the enjoyment they bring. Along with ravens, pigeons are among the few birds that fly seemingly just for the pleasure of flying, and not merely with some utility in mind. And well they should, as they, again like the ravens, and along with the falcons, are amongst the most superb avian athletes we know. They can fly for days on end if necessary, and have been known to average speeds of 125 kilmoetres per hour on their journeys. Morning chores around here are brightened by the spectacle of our pigeons on the wing, one moment mere specks high up and off to the horizon, and then close at hand, diving, twisting amongst the buildings, the wind shearing audibly through their pinions, their hues and forms marvelous against the backdrop of any sky, clear blue or against black storm clouds when they may appear as sparkling snow.
Pigeons are considered to be one of the most intelligent of birds, being able to undertake tasks previously thought to be the sole preserve of humans and primates. The pigeon has also been found to pass the “mirror test” (being able to recognise its reflection in a mirror) and is one of only 6 species, and the only non-mammal, that has this ability. The pigeon can also recognise all 26 letters of the English language as well as being able to conceptualise. In scientific tests pigeons have been found to be able to differentiate between photographs, and even differentiate between two different human beings in a photograph when rewarded with food for doing so. I suspect, truthfully, that many more creatures than we realize are on this level, we simply haven’t examined them for such traits.
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 and if conditions permit, keep both.
The common sooty pigeon of the streets
Spells all the grunge ground out by urbane life –
The thick air dulls his blotchéd wing, he eats
The gutter-slime, and courts his would-be wife
with gross inflations, sings with horrid calls,
Grim coos and gurglings, clatters when he flies
Streaks white-wash droppings on the city's walls,
and mummifies in attics when he dies.
But if transpose this self-same bird from these
Dull streets to water-running gorge-cut shale
He sets his wings into the rushing breeze
(Dihedral now explained) upwards he sails
And fills the broken niche. No less himself,
He fits, his forebears fit him for, that rocky shelf.
Cornell University, 1967-1968
I kept homing pigeons for a few years to train my bird dog. They became part of the homestead family quickly. Their navigational ability has been studied extensively. Their capability to "home" is still not completely understood...the four or five best theories are impressive. They can routinely be taken hundreds of miles from their coop and find their way back with ease. They are not trash eaters or dirty as many people think. They primarily eat seeds. And they are delicious, not just as squab [before they fledge] but as adults as well.
