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.

Coffee and Provocation



A Little More Hexane in Your Veggie Burger?
Mother Jones magazine, notes that "In order to meet the demands of health-conscious consumers, manufacturers of soy-based fake meat like to make their products have as little fat as possible. The cheapest way to do this is by submerging soybeans in a bath of hexane to separate the oil from the protein." Hexane, of course, is an EPA-regulated neurotoxin, but despite that fact, the FDA does not test for it. Read the article.

This Is Why You Defend the Second Amendment:
The U.S. Constitution says nothing about guns. Not a thing. What it talks about is the "right to keep and bear arms." If you remove that right, the state can actually march in and take your pocket knife. Think that's crazy talk? It's not if you live in the U.K., where a disabled man who kept a Swiss Army knife in his car's glove box has just gotten a criminal record for possessing an offensive weapon. The knife was not just in his glove box, by the way -- it was in a pouch in his glovebox, along with a small flashlight, a first aid kit, and waterproof matches.

This Is Why You Defend the First Amendment:
The Associated Press reports that: "Sarah Palin spoke to a crowd of about 16,000 attending an evangelical Christian women's conference in Louisville Friday night....She asserted that America needs to get back to its Christian roots and rejected any notion that 'God should be separated from the state.'" Great. Just what we need to be: a theocracy like Iran, Afghanistan, Saudi Arabia, and the Vatican.

Tasering Sheep on Meth:
In a study of Taser safety, scientists got a bunch of sheep hopped up on meth and then zapped them with tasers to see how they did with that. Read all about it.

Native American Genius:
W.T. Wallington's Forgotten Technology web site shows techniques he has developed to show how the stones for Stonehenge and the Pyramids might have been hauled, rotated, and lifted into place using nothing more than simple physics. Check it out by clicking on the picture on the home page, and clicking through the links at the bottom of each subsequent page. Yes this stuff works! No space ships or Martians needed -- or massive ramps either from what I can gather.

Doug's Expanding Menagerie:
Doug is rehabbing a red-shoulderd hawk and starting an adventure in bees, the animal most likely to kill you. Madness I say!

Dominance in Pigeons:
Who is the alpha pigeon? Researchers are studying it with little GPS backpacks.

The Garden of Cosmic Speculation:
The Garden of Cosmic Speculation was created by Charles Jencks and Maggie Keswick in Dumfries, Scotland in 1989. It contains bizarre and mind-blowing geometric patterns. Check it out! This is a private garden and open to the public only one day a year, so these pics are probably your only opportunity.

Whatever Happened to Sealyhams?
Sealyham's are a breed that was sucked into the kennel club vortex almost upon creation. For a web site documenting that, see this interesting, if obscure, web site on show sealyham terriers in the 1920s, '30s and '40s, complete with a pictures of what the Westminster show looked like at Madison Square Garden back then, and a little note about the first head of the "professional handler's association." Hat tip to Paul H. for the link!

Nice Blog!
If anyone wants to see what a fun life in Western Colorado looks like (complete with great photos), see the Dirt and Dogs blog and check out "the hunter and the hunted" post for a little amusement. Also a few pictures of Arizona in here. Of course, Jamie O'Neal claims there is no Arizona. I think Trina might disagree!

Vitamin C for Canine Snake Bites?
I am quite happy that we do not have to worry, too much about venomous snakes in my area; we are a little too far north for water moccasins, copperheads are way over-rated, and rattlesnakes are rare all over and generally confine themselves to rocky shelves and outcrops in the mountains. That said, not everyone is so fortunate and Jonathan from South African passes on this tip about Vitamin C shots as a treatment for snake bites in dogs. Does it work? There are reports on the internets that it does, but I have to say I am skeptical. Snakes do not always envenomate when they bite, and there's a lot of mis-identification of snake species as well. Still, when nothing else is there to help, break out the Vitamin C. It cannot hurt!

How Google Really Works



It seems I am not the only one writing about B.F Skinner and operant conditioning.

This morning I was sent a link to Google's description of how their search engine determines page rankings and search engine results.

As a Google user, you're familiar with the speed and accuracy of a Google search. How exactly does Google manage to find the right results for every query as quickly as it does? The heart of Google's search technology is PigeonRank™, a system for ranking web pages developed by Google founders Larry Page and Sergey Brin at Stanford University.

Building upon the breakthrough work of B. F. Skinner, Page and Brin reasoned that low cost pigeon clusters (PCs) could be used to compute the relative value of web pages faster than human editors or machine-based algorithms. And while Google has dozens of engineers working to improve every aspect of our service on a daily basis, PigeonRank continues to provide the basis for all of our web search tools.


Yes, you have to read the whole thing.
