BBC says that’s what’s going on in the Netherlands. The baboons were terrified, but no one knows why; The behaviour started on Monday evening, and only now are the 112 baboons becoming their normal, active selves again, said a biologist at Emmen Zoo. The zoo still has no idea what spooked the hamadryas baboons, but it is a good sign that some are now eating apples, biologist Wijbren Landman said. The zoo last saw such hysteria in 2007. “What frightened them? We don’t know, it’s a mystery. There have been many suggestions – an earthquake, escaped snakes, aliens, thunder,” Mr Landman told BBC News. “The other animals here are OK – they have lemurs, elephants and kangaroos as neighbours, and they show no sign of panic.” Might it be some kind of mass hysteria brought on by captivity? Or maybe they were just messing with the biologists….
These are prehistoric animals compared to their modern relatives and, for scale, a human. A human who’s interested in what they’re like… except when…
Look out! HELL PIG!
There are plenty more of the majestic giants (and some terrifying ones) at NPR’s Skunk Bear tumblog.
The New Horizons Long Range Reconnaissance Imager (LORRI) snapped this photo of Jupiter’s ring system on February 24, 2007, from a distance of 7.1 million kilometers (4.4 million miles).
This processed image shows a narrow ring, about 1,000 kilometers (600 miles) wide, with a fainter sheet of material inside it. The faint glow extending in from the ring is likely caused by fine dust that diffuses in toward Jupiter. This is the outer tip of the “halo,” a cloud of dust …

ABSTRACT: The planet Jupiter is 35 light-minutes from Earth (give or take a couple of minutes depending on where in its orbit the planet is).
So a robot floating in the turbulent winds of Jupiter would take that long to send a mes…
Three names for one little fish. And those are just the beginning.
I found this one on the Scientific Illustration tumblog, which quoted Wikipedia on the doree (etc.):
John Dory, St Pierre or Peter’s Fish, refers to fish of the genus Zeus, especially Zeus faber, of widespread distribution. It is an edible benthic coastal marine fish with a laterally compressed olive-yellow body which has a large dark spot, and long spines on the dorsal fin. The dark spot is used to flash an ‘evil ey…
These are ostensibly Cochin chickens, or forerunners of what we’d call Cochins today. They’re a breed with a *lot* of character, and are uniquely suited, temperamentally, for being “pet” chickens moreso than egg factories or walking meat supplies. Despite the name (after a part of India), they’re originally from China.
It’s the most Earth-like planet yet discovered. Kepler 452b sits in the “Goldilocks” zone around its star, not too hot and not too cold, and is about the same size (or is a little larger) and made of something like the same stuff as the planet we’re sitting around on right now. It takes 365 days to orbit around its sun, too. NASA’s calling it ou…
SONG: “National Primate Home.” [Download] (To download: double right-click & “Save As”) ARTIST: grant. SOURCE: Based on “Call for NIH research chimpanzees to be retired”, Nature, 6 July 2012, as used in the post “Chimp retirement plan.”. ABSTRACT: This was written in response to the latest SongFu2012 prompt, from Ken Plume (the fellow who organizes the whole thing):“It’s my birthday this month, so I’m taking this prompt and giving you – Write an upbeat birthday song that never explicitly states it’s a birthday song.”. I have a habit, which I suppose I’m trying to break, of sending friends a video of the They Might Be Giants song “Older” on their birthdays. I love a fugue, and the passage of time… but that’s not terribly upbeat in any sense of the word. So instead, I started with the story about the chimps. A birthday would likely not be celebrated at the NIH hepatitis lab, other than […]
Here’s an ape with plenty of character – plenty of, dare I think it, soul. This is not the first image from Brehm’s Tierleben (or “Brehm’s Life of Animals”) to have been featured on these pages. But it may be the one with the most thoughtful quality. This chimpanzee was alive before the Civil War broke out – before the Transcontinental Railway was completed – before the telephone was invented. And yet I can look at this face and think, “I know how you feel. I know what you’re thinking. I’ve thought the same thing, too.” I’m sure Alfred “Pharaoh” Brehm knew what I’m talking about.
That’s the idea behind a study by University of Oxford and the University of Auckland researchers in PhysOrg. The scientists found that our ability to live in lots of different social settings is what sets us apart from other primates: The study analysed patterns of social groups among living primates, as well as examining the ‘the root’ of the family tree, in 217 primate species. The researchers then used Bayesian data modelling to reconstruct the most likely explanation for how the grouping behaviour of primates evolved over 74 million years. Their key finding is that the main step change in social behaviour occurred when primates switched from being mainly active at night to being more active during the day. Primates started out as solitary foragers as by night they could survive by moving quietly on their own in the dark. However, once they switched to daytime activity, they could be seen and were more vulnerable […]
Not people hunting chimpanzees, Scientific American reports, but chimpanzees hunting monkeys: According to a study published May 9 in the American Journal of Primatology, this is the first documented case of a nonhuman primate significantly overhunting another primate species. (The taxonomy of Ugandan red colobus monkeys is in dispute. Some scientists consider them a species, Procolobus tephrosceles, whereas others identify them as a subspecies, P. rufomitratus tephrosceles.) The study examined nearly 33 years of primate census data (covering 1975 to 2007) and found that the endangered Ugandan red colobus monkey population dropped 89 percent during that time, mainly as a result of being hunted by common chimpanzees (Pan troglodytes).
It’s really hard to beat the Christian Science Monitor’s headline on this story…. Monkeys hate flying squirrels, report monkey-annoyance experts: “Human evolution occurred alongside primate evolution from a common mammalian ancestor,” [Kenji Onishi, an assistant professor of behavioral sciences at Osaka University,] told LiveScience. “Therefore, it is important to learn the evolution of primates in understanding the previous steps in human evolution.” … When Japanese giant flying squirrels glided over to a tree in the monkeys’ vicinity, adults and adolescent macaques started hollering at it threateningly, the researchers report. Young macaques screamed and mothers scooped up their infants, while adults and high-ranking males in particular went and physically harassed the offending squirrel. Onishi said other researchers have observed macaques responding in a similarly aggressive manner to birds that prey on the monkeys, such as the golden eagle and mountain hawk eagle. These raptors glide and swoop much like the flying squirrels. Upon closer inspection up […]
Science Daily spoils the myth of the peaceful forest apes that live idyllic lives with no concept of ownership. Apparently, the brutes fight long wars over land rights: During a decade of study, the researchers witnessed 18 fatal attacks and found signs of three others perpetrated by members of a large community of about 150 chimps at Ngogo, Kibale National Park. Then in the summer of 2009, the Ngogo chimpanzees began to use the area where two-thirds of these events occurred, expanding their territory by 22 percent. They traveled, socialized and fed on their favorite fruits in the new region. “When they started to move into this area, it didn’t take much time to realize that they had killed a lot of other chimpanzees there,” Mitani said. “Our observations help to resolve long-standing questions about the function of lethal intergroup aggression in chimpanzees.” Graphic descriptions of war crimes at the link.
Nature says it’s true: Rhesus monkeys will trade items of value – in this case, juice – in return for sexy monkey booty shots: The researchers gave captive male rhesus macaques two options: a drink of cherry juice, or a different-sized shot of juice and the chance to look at one of a range of pictures of their troop members for just over half a second. By varying the amounts of juice, the team worked out how much the monkeys valued each image. “Monkeys are basically juice experts; they’re very sensitive to the differences,” says team member Robert Deaner. Monkeys would take a juice cut to look at powerful males’ faces or the perineum of a female, Deaner and his colleagues report in Current Biology. But to persuade the monkeys to stare at subordinate males, the researchers had to bribe them with larger drinks. …[T]he juice-to-picture exchange rate was highest for images of female rears. […]
And, Wired says, we’re just about able to understand their vocabulary… and their grammar: Lemasson’s team previously described the monkeys’ use of calls with specific meanings in a paper published in November. It detailed the monkeys’ basic sound structures and their uses: “Hok” for eagle, “krak” for leopard, “krak-oo” for general disturbance, “hok-oo” and “wak-oo” for general disturbance in forest canopies. A sixth call, “boom,” was used in non-predatory contexts, such as when calling a group together for travel or arguing with neighboring groups. Impressive as that was, however, it was still relatively one-dimensional, not much different from verbalizations heard in many animal species, from other non-human primates to songbirds. The team’s latest findings, published Monday in the Proceedings of the National Academy of Sciences, describe something far more complicated: syntax, or principles of word sequence and sentence structure. Though some researchers have ascribed syntax to animals, it’s never been formally demonstrated — until now.
OK, not monkeys, but apes, New Scientist says, have been caught making musical instruments: The orang-utan’s music, if you can call it that, is actually an alarm call known as a “kiss squeak”. “When you’re walking the forest and you meet an orang-utan that not habituated to humans, they’ll start giving kiss squeaks and breaking branches,” says Madeleine Hardus, a primatologist at the University of Utrecht in the Netherlands, who documented the practice among wild apes in Indonesian Borneo. She contends that orang-utans use leaves to make kiss squeaks to deceive predators, such as leopards, snakes and tigers, as to their actual size – a deeper call indicating a larger animal. Leaf-enhanced kiss-squeak musician videos are at the link.
The AP is laughing it up over sensitive research into what makes apes laugh: To investigate that, Marina Davila Ross of the University of Portsmouth in England and colleagues carried out a detailed analysis of the sounds evoked by tickling three human babies and 21 orangutans, gorillas, chimps and bonobos. After measuring 11 traits in the sound from each species, they mapped out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online Thursday in the journal Current Biology. You can read the article summary here, including the phrase: “the current work examined the acoustics of tickle-induced vocalizations.”
The Monkey Wire (no, really) is jumping with news of a study that shows chimpanzee babies are smarter than humans: Daily Express Professor Kim Bard, of the Centre for the Study of Emotion at the University of Portsmouth, studied the care records of 46 baby chimps at risk of death through neglect by their mothers. A group of 17 given “responsive care” had human carers looking after them 20 hours a week. They tended to their physical and emotional needs, grooming, feeding and interacting with them. Professor Bard then looked at a second group of 29 given standard care catering only for physical needs. She compared the results with standard measurements of the intellectual development of human babies aged nine months. Chimps given responsive care scored 110, the average human baby at nine months 100 and chimps given only basic care 91. … She also found that babies in Romanian orphanages performed even worse than […]
