Dog Mummy, Egyptian Museum (Photograph: Richard Barnes)
National Geographic recently did a feature on mummified animals exhibited in the Egyptian Museum.
I think the mummified dog (above) must be a saluki.

“There goes my life’s work.” George Monbiot (the original moonbat) laments the impact of Climategate. The experts, he observes, are “Like squabbling evangelical churches in the 19th century, they can form as many schismatic sects as they like, nobody is listening to them any more.”

The recent New Yorker profile of Paul Krugman features some particularly fine examples of superbia.
“We were the only textbook that incorporated the financial crisis, as we were chronically late. We were supposed to have the manuscript delivered in August or September, and by October we were still working, and we just said, ‘We can’t send it out like this, too much is going on.’ We were really in nail-biting territory, because you have to get it to the printers by a certain date or you miss the academic year.”
“We were right in the middle of that when the Nobel Prize committee called, and Robin’s reaction was ‘We don’t have time for this! ...
“Paul is really averse to being drawn into a social network, to being groomed,” Wells says. “He doesn’t go to Washington because he doesn’t want to fall into that. As a spouse, you have your little list of things that you jokingly won’t forgive your spouse for. Right after he started writing for the Times and attacking George Bush, we got an invitation to have dinner with Paul Newman and his wife, but he wouldn’t go. And now he’s dead.”
“It was inconvenient,” Krugman says. “I just don’t get any joy out of thinking, Oh, here I am with the movers and shakers. It would have required really discombobulating my schedule just to be able to say I’d had dinner with Paul Newman, and it’s not worth it.”

Richard Murphy explains to his readers why he fights.
Tory parliamentary candidates have undergone training by a rightwing group whose leadership has described the NHS as “the biggest waste of money in the UK”, claimed global warming is “a scam” and suggested that the waterboarding of prisoners can be justified.
This is the reality of the libertarian right – openly hostile to humanity at large, embracing abuses of human rights, putting profits before else, contemptuous of the needs of the majority, denying facts when it suits them, seeking to destroy society as we know it, and wishing to make life for most considerably worse than it is now to advance their own enrichment.
That’s why I take them on here – and the bogus economics some of them use to support their arguments.

Moscow commuters smile at sleeping metro dog
Andrei Poyarkov of the Severtsov Institute of Ecology and Evolution in Moscow has been studying his city’s population of stray dogs for 30 years. FT.com has a very interesting article describing some of his conclusions.
What is particularly interesting is the way, as is sometimes the case with Europeans, the Russians fail to see the necessity of the American Protestant “capture, euthanize, and sterilize” tidy-everything-up ameliorist approach. Muscovites don’t mind living with stray dogs and are willing to stand aside and let Nature take its course, even in a city.
“With stray dogs, we’re witnessing a move backwards,” explains Poyarkov. “That is, to a wilder and less domesticated state, to a more ‘natural’ state.” As if to prove his point, strays do not have spotted coats, they rarely wag their tails and are wary of humans, showing no signs of affection towards them.
The stray dogs of Moscow are mentioned for the first time in the reports of the journalist and writer Vladimir Gilyarovsky in the latter half of the 19th century. But Poyarkov says they have been there as long as the city itself. They remain different from wolves, in particular because they exhibit pronounced “polymorphism” – a range of behavioural traits shaped in part by the “ecological niche” they occupy. And it is this ability to adapt that explains why the population density of strays is so much greater than that of wolves. “With several niches there are more resources and more opportunities.”
The dogs divide into four types, he says, which are determined by their character, how they forage for food, their level of socialisation to people and the ecological niche they inhabit.
Those that remain most comfortable with people Poyarkov calls “guard dogs”. Their territories tend to be garages, warehouses, hospitals and other fenced-in institutions, and they develop ties to the security guards from whom they receive food and whom they regard as masters. I’ve seen them in my neighbourhood near the front gate to the Central Clinical Hospital for Civil Aviation. When I pass on the other side with my dog they cross the street towards us, barking loudly.
“The second stage of becoming wild is where the dog is socialised to people in general, but not personally,” says Poyarkov. “These are the beggars and they are excellent psychologists.” He gives as an example a dog that appears to be dozing as throngs of people walk past, but who rears his head when an easy target comes into view: “The dog will come to a little old lady, start smiling and wagging his tail, and sure enough, he’ll get food.” These dogs not only smell who is carrying something tasty, but sense who will stop and feed them.
The beggars live in relatively small packs and are subordinate to leaders. If a dog is intelligent but occupies a low rank and does not get enough to eat, he will separate from the pack frequently to look for food. If he sees other dogs begging, he will watch and learn.
The third group comprises dogs that are somewhat socialised to people, but whose social interaction is directed almost exclusively towards other strays. Their main strategy for acquiring food is gathering scraps from the streets and the many open rubbish bins. During the Soviet period, the pickings were slim, which limited their population (as did a government policy of catching and killing them). But as Russia began to prosper in the post-Soviet years, official efforts to cull them fell away and, at the same time, many more choice offerings appeared in the bins. The strays flourished.
The last of Poyarkov’s groups are the wild dogs. “There are dogs living in the city that are not socialised to people. They know people, but view them as dangerous. Their range is extremely broad, and they are predators. They catch mice, rats and the occasional cat. They live in the city, but as a rule near industrial complexes, or in wooded parks. They are nocturnal and walk about when there are fewer people on the streets.”

Peanut worm (Sipunculida)—Sipunculid worm jelly (土笋冻) is a delicacy in the town of Xiamen in Fujian province of China. Above: Sipinculus nudus
Jeremy Alban Dorman, in the Telegraph, reminisces about his gustatory adventures in the further reaches of Chinese dining.
While in China, I often felt I was rather like William Buckland, the 19th-century naturalist, who was noted, among other eccentricities, for attempting to eat his way through the entire animal kingdom. There seemed to be nothing the Chinese wouldn’t ingest. I never came across stir-fried sponge, though I won’t eliminate the possibility of there being a sponge restaurant somewhere in Guangdong province. All other members of major, or in the case of the sipunculids, minor, animal phyla find themselves on to Chinese menus, occasionally unwanted, of course, like the nematodes I once discovered wriggling on top of a bowl of noodles.
Over my years in China I added jellyfish, sea cucumber, silk worm pupae, cicada, scorpion, frog, snake, turtle and, I am ashamed to say, dog, as well as the sipunculids, to my list of new gustatory experiences. I also tried various odd parts of vertebrates that we wouldn’t normally eat such as bull’s aorta, pig’s lungs, pigs’ feet tendons and chickens’ feet.
The Chinese place extraordinary value on some foods which we consider worthless, like the unfortunate sharks’ fins, and sea cucumbers, which can sell for up to four hundred pounds per half kilo, yet have no taste and little nutritional value at all. I was so impressed by the demand for these humble marine vacuum cleaners that I made vague plans to begin farming them in east Africa. Perhaps fortunately, no-one else considered it a worthwhile endeavour, so I became a teacher instead.
The Chinese appear to derive more pleasure from the texture of their food than the actual taste. An army colonel I once taught told me that he loved nothing more than to munch on a plate of ducks’ beaks while having his evening beer. A shop near my last apartment sold nothing but ducks’ beaks, necks and feet and assorted internal organs – a sort of duck spare part shop. Similarly I was once taken to a fish-head restaurant. The head is considered to be by far the best part of the fish, and I got a sudden vision of fishermen filleting their catch on the way home from sea, tossing the heads and vertebrae into their baskets, and hurling the juicy fillets to the gulls.
Some Chinese dishes are remarkable for the sheer incongruity of their ingredients. A Sichuan dish I once tried consisted of eel, tripe, blood pudding, bean sprouts and noodles – any possible taste was obliterated by the hundreds of burning chillies. Another unlikely concoction I tried only once was baby squid fried with green peppers and pig’s heart. A Shandong speciality is made up of pork pieces (mostly bone), fish pieces (likewise), seaweed and chickens’ heads.
Trying to replicate such dishes in one’s own kitchen, should one wish to, is always doomed to failure. I well remember my first encounter with a packet of jellyfish. I chose the particular brand because the instructions were written in English, of sorts.
“It is nutritional foods of you and dainty dish of perfect daily”, it read helpfully. “Stir-fry is put jellyfish in boiler when added meat, shallot, ginger, garlic and stir-fried”. I followed the instructions, and not surprisingly, the jellyfish turned into water and evaporated.
The sipunculids, by the way, tasted only of soy sauce and ginger. I have since become a vegetarian.

London Times:
Czech photographer Vaclav Silha shooting on the banks of the Grumeti River in the Serengeti National Park, Tanzania happened to be in the right place at the right time to record a crocodile’s untimely end.
(An) incautious croc (Crocodylus niloticus) got too close to a female (Hippopotamus amphibius) who had calves and the whole group gathered into a defensive circle.
“The crocodile suddenly raced across the backs of the hippos. It might have panicked and thought it was an escape route. It was the worst choice the reptile could ever have made. And it was definitely its last.
“The island of hippos erupted with teeth and all I could see was the crocodile being repeatedly crushed in their huge mouths. His body slipped below the water and I didn’t see him again.”

Cropped and enlarged “Boa” photo
Despite the “internet sensation” claim, Ananova is really the only news source on this one.
A photograph purporting to show a 55ft snake found in a forest in China has become an internet sensation.
It was originally posted in a thread on the website of the People’s Daily, the official Communist Party newspaper in China.
The thread claimed the snake was one of two enormous boas found by workers clearing forest for a new road outside Guping city, Jiangxi province.
They apparently woke up the sleeping snakes during attempts to bulldoze a huge mound of earth.
“On the third dig, the operator found there was blood amongst the soil, and with a further dig, a dying snake appeared,” said the post.
“At the same time, another gold coloured giant boa appeared with its mouth wide open. The driver was paralysed with fear, while the other workers ran for their lives.
“By the time the workers came back, the wounded boa had died, while the other snake had disappeared. The bulldozer operator was so sick that he couldn’t even stand up.”
The post claimed that the digger driver was so traumatised that he suffered a heart attack on his way to hospital and later died.
The dead snake was 55ft (16.7m) long, weighed 300kg and was estimated to be 140 years old, according to the post.
However, local government officials in Guiping say the story and photograph are almost certainly a hoax as giant boas are not native to the area.
Anannova seems to have gotten the story from QuirkyChina, which claims to be quoting the People’s Daily for November 11th, but no such story turn up in a search of the English language edition of the paper’s web-site.
The use of the term “boa” is obviously inaccurate. Boa constrictors are native to the New World. The visible markings on the snake’s back, I think, identify it clearly enough as a reticulated python. And Chinese English news reports do clearly routinely refer to pythons (native to Asia) as “boas.”
This 40 k. (88 lbs.), 4 m. (13’) long reticulated python found by Yunnan villagers in this October 22, 2006 story is referred to as a “giant boa.”
There is a problem with range. Guping is a bit north of the generally described range of Python reticulatus.

Wikipedia estimated range of Reticulated Python (Python reticulatus)

Jiangxi Province, China
And there is a problem with the size. The photograph is obviously calculated to mislead. The snake is hanging from the bucket in the extreme foreground in an effort to induce viewers to take the people and cab behind as an indication of scale. If someone could identify the model of the backhoe, and could determine the actual size of the digging bucket, it would be pretty easy to come up with a more accurate estimate of the actual size of the snake.
Estimates of how large reticulated pythons can grow vary. Wikipedia says “more than 28 feet (8.7 m),” quoting Murphy/Henderson (1997). Wall (1926) proposes 30’ (9.14 m.). Oliver (1958) goes all the way up to 33’ (10.06 m.).
Yet, there is a news agency account, dated January 8, 2004, describing the capture in Indonesia of a nearly 49 foot (14.9 m.), 990 pound (450 k.) monster reticulated python, complete with 0:33 video.

Humans… They’re what’s for dinner.
One of the participants on a bamboo fly rod list forwarded the link to this 2007 YouTube video of a mountain lion looking into the window of a Colorado home in very much the manner of a house cat sitting patiently outside a mouse hole.
The lady doing most of the filming seems a bit overconfident in the ability of window glass to serve as an impenetrable barrier to wildlife. One can see the lion giving some serious consideration to having a try. Fortunately he decides in favor of prudence, or I expect we’d have never seen this video.
Apparently, the lion had been seen hanging around the vicinity of these people’s house before the video was made. The sensible thing to do would have been to shoot this particular lion.

Asiatic black bear (Selenarctos thibetanus)
Strategy Page reports that a formidable new ally, a powerful fighter particularly skilled in mountain warfare, recently joined the Western Anti-Jihadist Coalition.
In Indian Kashmir, an Islamic terrorist leader, and one of his followers was killed by a black bear. Two other terrorists were wounded, but were able to flee to a nearby village. Although the terrorists were armed with assault rifles, the bear attacked quickly, and at night, and the men were unable to use their weapons in the restricted confines of the cave. Apparently the bear was going to use the cave to hibernate in, and was upset to find that the terrorists had moved in. The four terrorists thought the cave was abandoned, and a good place to hide out in.
The Asiatic Black Bear is related to the American black bear, but is larger (up to 400 pounds for an older male), and is much more aggressive towards humans. The Asiatic bear has a more powerful jaw, and bigger claws.

Here is a short 0:53 video from Finland showing a Golden eagle (Aquila chrysaetos) attacking and killing a reindeer calf (Rangifer tarandus).
BBC:
A BBC natural history film crew gathered the extraordinary footage along a reindeer migration route in northern Finland.
It finally proves this eagle species does occasionally hunt reindeer, something suggested by forensic evidence and the local Sami people.
The crew filmed the behaviour while capturing footage of the reindeer migration for the BBC natural history series Life, though the images were shot at too far a distance to be included in the final cut of the high definition programme.
In the last 100 yards it went into a low powerful glide and hit the back of a calf
Television producer Dr Ted Oakes, cameraman Mr Barrie Britton and scientist Mr Harri Norberg set out to film the hunt along the northern edge of Finland.
For his PhD thesis Mr Norberg has spent the past few years studying how predators interact with the reindeer (Rangifer tarandus), which are known as caribou in North America.
Mr Norberg would tag calves, then search out those that had stopped moving to find out what had killed them.
By examining the bodies and the size and shape of claw, bite or talon marks, he ascertained that the majority of reindeer calves killed in the region had been attacked by eagles. ...
More often than not the golden eagles (Aquila chrysaetos) appeared to attack white calves, rather than tan or brown ones, though the crew did not know why.
According to Mr Norberg, it is usually immature golden eagles that kill the calves.
However, he also believes the birds occasionally hunt adult reindeer.
Another larger species of eagle lives in the region, the white-tailed eagle (Haliaeetus albicilla), but this bird is less aggressive than the golden eagle, and will often be chased off a reindeer carcass by its smaller relative.
The Sami people that live in the area say they have seen white-tailed eagles also killing reindeer, but this behaviour has yet to be scientifically documented.

Southern flying squirrel emerges from beneath dog dish (Photographs: Karen L. Myers)
Karen heard activity in the dining room ceiling yesterday evening, and the cats were definitely interested.
When I came downstairs this morning, I found the white cat, Petra, had managed to enter the off-limits living room by leaping over the cat gate and had trapped herself inside. A little while later, Karen found the source of all the nocturnal activity.
A flying squirrel (Glaucomys volans—the Southern variety) had gotten itself cornered by the housecats at the dining room fireplace.
We herded the squirrel into the kitchen and in the direction of the backdoor. While it was considering making a break for it, instead of turning the corner, to hide under the Hoosier cabinet, Karen cleverly popped a metal dog dish over it.
All we had to do then was slide the 2010 Master of Foxhounds calendar (still wrapped in cellophane) under the dog dish, and voilá! the squirrel was safely confined and portable.
We took him out to an old stone foundation in the backyard, where I slid the calendar aside just enough to allow an exit.
This is actually the second flying squirrel successfully evicted unharmed in the three years we’ve been here.

Spider cloth displayed at the American Museum of Natural History
Wired:
“To produce this unique golden cloth, 70 people spent four years collecting golden orb spiders from telephone poles in Madagascar, while another dozen workers carefully extracted about 80 feet of silk filament from each of the arachnids. The resulting 11-foot by 4-foot textile is the only large piece of cloth made from natural spider silk existing in the world today.”
The project was modeled on the work of a Victorian-era French missionary, Jacob Paul Camboué, who invented a machine to extract silk from up to 24 spiders at a time.

John Lichfield reports that Asterix’s beloved sanglier has multiplied five times over the last two decades.
In the forest close to our house in Normandy, we have neighbours that we never see. Occasionally, you might spot one sprinting across the road late at night. Each autumn, brutal-looking men in paramilitary uniforms invade the forest with dogs and horns to try to shoot them.
The other morning, for the first time in 11 years, I saw one of our neighbours in broad daylight. He was loitering in the middle of the road. When my car came along, he stared at me insolently and then trotted off into a field of almost-ripe maize.
Our neighbours are sangliers, or wild boar. Their population is exploding. Despite the best efforts of the men in paramilitary uniforms (who often seem to end up shooting one another), the wild boar population of France has increased five-fold in the last 20 years to reach an estimated one million.
Several reasons are given for their proliferation. The great hurricane of Christmas 1999 left French forests in such a jumble that the boar have many more places to hide from the hunters. The spread of cereal fields into traditional beef and dairy country (like Normandy) has given them a new food supply. They are especially partial to maize.
Last week, the wild boar, sanglier or Sus scrofa was officially declared a public menace. Over 15,000 road accidents a year – two-thirds of all French road accidents are attributable to animals – are caused by wild boar dashing across roads at night without looking both ways. The environment minister, Jean-Louis Borloo, has ordered an anti-boar campaign, including official culls and, possibly, a longer hunting season.
