Maladaptive Pigeons at the Hand of Man


The Rock Dove or Rock Pigeon, from which all domestic pigeons derive.

Dogs are not the only animals that have been selected for function and dysfunction at the hand of man.

And yes, this is just a partial list!





As I noted some years back
, there is a breed of pigeon called a "roller" where flocks go into a kind of synchronized neurological fit causing them to roll over and tumble in mid-air -- the kind of activity that tends to attract hawks. Talk about maladaptive!

In addition to rollers, there are racing or homing pigeons which look very much like natural rock doves (i.e. wild pigeons), but which may have a little more speed and slightly better orienteering skills.




Of course, as with dogs, many of these breeds are only slighty different variations from others of a very similar type, while others look suspiciously like odd-looking versions of the common feral form you might see in any city park, while still others look like diseased mutants.

But isn't that true of dog breeds as well?!



Some of the pigeons that have been crafted
by the hand of man are truely beautiful and fly very well, while others are bizarre looking and fly less successfully.

In the bizarre catagory is the Blue Pouter, pictured below, which is an ornamental breed with long legs, an extruded body, and an amazing inflatable crop.




There are quite a few types of Pouters, and the function of one type, the "Horseman" Pouter is to serve as a "thief" bird. It turns out that a swollen crop is a bit of a turn on to female pigeons, and so female pigeons can sometimes be seduced to follow the Horseman Pouter back to his coop.



Charles Darwin was quick to notice the amazing varieties of livestock being produced by breeders in his day, and he was especially attentive to chicken and pigeon breeders as he himself had first noticed wide variation from an intermediate type when observing finches on the Galapagos Islands.

When Darwin came back to Britain in 1836, he began to correspond with dog, chicken, sheep, cattle and pigeon breeders from around the world as he worked out his theories of speciation through natural selection.

In 1855, he built his own pigeon loft and began raising a wide variety of pigeons himself.

For the rest of that story I recommend a lengthy tour through the excellent web site, Darwin's Pigeons.





A final note: the beautiful pigeon illustrations shown here are the work of Gary Romig, and are for sale at his web site.

They are redone versions of illustrations which first appeared in Robert Fulton's The Illustrated Book of Pigeons, published in 1878. A companion volume, by Lewis Wright, was called The Illustrated Book of Poultry.
