Darren the waving goat: Your new YouTube sensation

A U.K. goat named, rather inexplicably, Darren (really? a goat named Darren?) is becoming a worldwide superstar for his ability to perform an impressive trick: waving to his fans while standing on his hind legs. 

Darren, an Anglo-Nubian goat, makes his home at White Post Farm near Nottingham, England, where he lives alongside not only other goats but also sheep, pigs, cows, llamas, donkeys, ponies, chickens and even wallabies and deer.  According to Metro U.K., Darren spent months perfecting his signature trick after seeing a visiting group of children wave when they left his pen.

Now the goat performs his trick with gusto, much to the delight of visitors to White Post Farm, a popular destination for school groups.  Farm staff caught Darren waving on video, uploaded it to YouTube -- and voila, a star was born. 

According to Anthony Moore, the farm's marketing manager, Darren enjoys the adulation his strange talent brings him, but his fellow farm-dwellers are more jealous than impressed.  "All the other goats have worked out it gets him extra attention and food, so now they've started trying to copy him," Moore told Metro U.K. "He loves it."

Jeepers creepers: Bedbug-sniffing dogs save the day

Trained dogs sniff out drugs in schools, detect bombs in airports, and even chase geese away from golf courses, but now trainers are focusing their efforts on another type of smart canine: bedbug-detection dogs. 

Today, L.A. Times reporter Bob Drogin wrote about the hard-working animals who sniff out infestations of real-life bedbugs -- those tiny, blood-sucking pests that leave itchy, painful welts -- in apartment buildings, hotels and office buildings so people really can sleep tight. This pest problem has become more than just a childhood scare tactic: Bedbugs are very real.

Many pest-control companies are now purchasing the dogs from two main trainers in Florida, who sell the dogs for up to $9,500 each. The dogs receive treat rewards whenever they alert for bedbugs, so experts caution against some exterminators whose dogs report false alarms, allowing the company to tack on extra charges.

We hope that this means the old adage will soon become a meaningless good-night saying once again.

The Heidi Chronicles, Chapter 51: Waiting on Wisteria Lane, Part 2

Last week, you read about our first day on the set of “Desperate Housewives,” cast as background actors, “Neighbor with Dog.”  As happens frequently in the TV biz, some of the extras called that day didn’t get used – but were asked to come back the next day. We learned that, for a background actor, everything is always is subject to change.

This time, instead of getting lost on the way to Wisteria Lane, a van picked us up at the parking lot at Gate 3. I had learned from our van experience the day before that, when nervous, Heidi turns into a very large lap dog -- so this time I was careful to get into the vehicle before the dog to make sure she didn’t once again surprise some other actor with a free lap dance.

We were whisked straight to the costume and makeup-and-hair trailers.  There, we met one of our new friends from the day before –  Lauren Hicks, who had won out over the competition for the “Busty Waitress“ role and had brought along the requested assortment of fancy bras to complement her low-cut white top.

My more conservative outfit – and Heidi’s bandanna – met with approval, but I had to leave Heidi in the care of another actor while I went into the trailer for a hair makeover. I sat one chair away from series star Marcia Cross as hairdressers fluffed her long red locks, and super-glued mine into a chignon that could withstand El Niño.

Then it was back into the van – today not headed to Wisteria Lane, but to a different set, an upscale outdoor cafe.  Apparently, “Neighbor with Dog” was about to become “Restaurant Guest with Dog.”

Your morning adorable: Rooster gives a high-five

Poor chickens often get a bad rap. While they're sometimes seen as unintelligent little grain-eating automatons, many are actually capable of putting those tiny little brains to use with tricks more commonly seen being performed by dogs.

Evidence: Foghorn Leghorn, the rooster wunderkind who knows how to give his owner a high-five (well, truthfully, more of a low-five).  OK, it's not rocket science -- but considering his brain is about the size of a human fingernail, we're suitably impressed.

In fact, some dog trainers even practice clicker training on chickens, rewarding the little guys with food when they perform behaviors their trainers wish to reinforce. In this way, chickens can be taught to flap, squawk and even perform more intricate tricks on command!  (These performing chickens have a leg-up on our own terrier mutts, both of whom ran from the room in terror when we attempted to get them used to the sound of the clicker.) All of this just goes to show, we suppose, that it's not the size of your brain, but what you do with it that counts.

Princess the camel won't pick Eagles games in protest over Vick

There's a camel in New Jersey who has a talent in choosing the winning team of pro football games. Last year Princess of the Popcorn Park Zoo accurately predicted the winners of 17 of 21 NFL games, including choosing the Pittsburgh Steelers to win the Super Bowl.

But to protest the Philadelphia Eagles' recent pickup of convicted animal abuser Michael Vick, Princess, who once belonged to heiress Doris Duke, won't entertain any games involving the quarterback's new team.

How does the camel choose her winning teams? According to the Associated Press, John Bergmann, the zoo's general manager, picks a game scheduled for that week, then he writes one team's name on one hand and the other team's name on his other hand. Bergmann then puts graham crackers in his hands and whichever hand the 2,600-pound animal licks first is the team she has chosen. 

Laugh all you want, but if you could pick NFL games accurately 81% of the time, you'd be laughing all the way to the bank.

Metallica: Not just for metalheads anymore, monkeys are fans too, a new study says

Animals prefer silence or sounds of their own species to human-made music, according to a new study published in the Royal Society Biology Letters and reported by the Discovery Channel. For some reason, that incites images of gorillas shaking their fists, screaming, "Will you kids turn down that goshdarn racket!"

What's even more interesting is that researchers found monkeys reacted calmly to Metallica's music, an apparently surprising discovery.

There appeared to be little explanation as to why the primates enjoyed the heavy-metal music. We're tempted to offer some guesses pertaining to the comparative intelligence of metalheads, but we don't want to insult any of our valued readers (or, for that matter, monkeys).

The research still doesn't explain why members of two different species can appreciate Metallica and why we cringe every time someone plays "One" on "Guitar Hero."

Rooks show there may be some truth to Aesop's fable 'The Crow and the Pitcher'

New research shows not only that rooks, crow-like members of the corvid family of birds, not only have impressive reasoning skills, it also shows that one of Aesop's fables may not be just a story after all.  

In the well-known fable in question, "The Crow and the Pitcher," a thirsty crow is confronted with a problem: A pitcher that contains water, but at too low a level for the bird to reach. The clever crow hatches (no pun intended) a plan and puts it into action, dropping pebbles into the pitcher until the water is raised to a level at which it can drink.

Researcher Christopher Bird of the University of Cambridge (who has previously made headlines with his bird-intelligence experiments -- and yes, that's his real name) and his colleague, Nathan Emery of Queen Mary University of London, found in their recent study that the fable isn't far from reality. 

For the study, they offered wax worms to four rooks, each of whom was raised by hand and five years old. But even if you're a rook, there's no such thing as a free lunch; the birds had to work for their food.  Bird and Emery placed the wax worms in narrow beakers partly filled with water, but at a level too low for the rooks to reach the worms.  Next to the beakers, they placed piles of stones. 

Cats know what they want, and a new study shows they know how to get it by purring

If your cat knows just what to do to convince you it's feeding time, a new study will help explain the scientific reason why.  For the study, to be published in Tuesday's edition of the journal Current Biology, researchers identified and examined a particular type of vocalization they termed "solicitation purring."

Solicitation purring "is producing the low fundamental frequency and its harmonics by muscular activation ... but also voicing a cry, probably with the inner edges of the vocal folds, which is then superimposed on the sound's frequency spectrum," the study's lead author, Karen McComb of the University of Sussex, told Discovery News. 

The resulting purr is not just any purr but also contains the hint of a more high-pitched cry that, the researchers suspect, reminds cat owners on some level of a crying human baby.  Most important, the researchers found, solicitation purring was effective in conveying urgency to human listeners.

The researchers learned that cats produce the solicitation purr only when they're with a human they know well.  "Remember, these cats have years to train up their owners," McComb told U.S. News & World Report. "They learn to dramatically exaggerate this cry embedded within the purr because it proves effective in getting their owner to respond."  So in order to conduct further testing, it was necessary to have cat owners record their pets' vocalizations. 

Cats and string: It's a tangled relationship after all

Sorry, cat people. Although your pets of choice are independent, clean and able to use a litter box, dogs have at least one leg-up on them: They're more able to understand the concept of cause-and-effect. Or so says psychology lecturer Britta Osthaus, who recently conducted a study on cats' thought processes using 15 feline subjects.

To test the cats, Osthaus and two graduate students attached treats like fish to pieces of string and hung them below a plastic screen.  (In this way, the cats could see the treats but were unable to reach them.)  Would the cats, she wondered, be able to figure out that they could pull the treats closer to themselves by pulling on the end of the string?

The answer: Sort of.  When the cats were presented with just one "baited" string, they were able to make the connection between string and snack, the Guardian reported.  But when Osthaus and her team made things trickier, the cats were unable to keep up.

To increase the difficulty of the task, the team added "decoy" strings, without treats attached. Now the cats had to choose between two strings, one with and one without a treat, either parallel to each other or crossed.  Faced with two strings, none of the cats were able to consistently choose the one connected to the treat.  (Most of them chose the correct string at least part of the time, but interestingly, one cat chose incorrectly each time he was presented with the crossed-string test.)

Crows and magpies show researchers their smarts

Stories abound about the wily crow's ability to form seemingly complex thoughts.  (Personally, we knew a man whose job duties occasionally included shooing the pesky birds away from the doors of a busy office building.  The flock learned to recognize his uniform and specifically sought him, and others in similar clothing, out for dramatic dive-bombings.)

But until fairly recently, scientists haven't given the birds much credit for intelligence.

"In the past, people thought birds were stupid," Christopher Bird (yes, his real name) of Cambridge University's zoology department told BBC News.  But several recent studies show that the corvid family of birds -- which includes crows, ravens and magpies, among others -- may have been underestimated all these years, especially where reasoning, memory and tool-making abilities are concerned.

One notable instance of corvid intelligence was first shown by a German research team last year.  The team studied magpies using the mirror test, pioneered by scientist Gordon Gallup in 1970.  The test measures subjects' self-awareness by determining whether or not they recognize their reflected images in a mirror as themselves.  A mark is placed on the subject, in an area of the body not visible without a mirror.  If the subject recognizes the mirror image as itself, the reasoning goes, it will try to remove the mark when it notices it in the reflection.
