Friday Fun: Mother Bear Rescues Cub From a Tree

Isn’t it great how the sibling seems to try and help the mother.

Scottish Highland Wildcats

Once again remote camera monitors have captured wild cats. What fun 🙂 Cameras capture secret life of the ‘Highland tiger’

A new research project in the Highlands has provided a rare insight into the secret world of one of Britain’s most endangered and elusive species.
…
Motion detectors and infra-red technology allow the devices to capture images of passing animals over a period of days, weeks or even months. The project is still in its early stages but the cameras have already provided images of Scottish wildcat – popularly known as the Highland tiger – and other animals, including golden eagles.

“Wildcats are very shy, secretive animals. They are active mainly at night and it’s really difficult for people to get close enough to watch them properly. These camera traps are an excellent way of us getting a much better insight into where wildcats live, when they’re active, and what habitat they’re using.”
…
Experts believe the Scottish wildcat population has fallen to about 400, and work is under way to prevent the species becoming extinct.
…
“The major threat to wildcats these days is hybridisation, or inter-breeding, with domestic cats. “Although they are quite different and have a completely different temperament, they are actually quite closely related genetically to domestic cats so they can produce fertile hybrids.

Critter Cam: Sea Lion versus Octopus

Octopus vs. Sea Lion – First Ever Video

Sea lions fitted with GPS trackers and a National Geographic Crittercam are taking scientists on amazing journeys to previously unknown marine ‘hot spots.’ These areas are important not only for providing the sea lions’ food, but also for maintaining fish populations.

The Crittercams were deployed at Dangerous Reef in Spencer Gulf, a rocky island the size of a football field, and home to the biggest Australian sea lion colony.
…
Dr. Page says, “One important discovery is that the sea lions always feed on the sea floor” and they don’t eat open ocean fish, known as pelagic. “This is critical information because the marine parks are being set up to protect sea floor habitats,” a move that the scientists can now confirm will protect critical sea lion resources.

In one of the more spectacular pieces of Crittercam video so far, we can see this female working hard to handle a challenging prey item – a large octopus. Too big to swallow in one gulp, she drags it to the surface where she can breathe while she works at breaking it down into bite-size pieces.

Surprise Shrimp Under Antarctic Ice

A three-inch long Lyssianasid amphipod found 600 feet beneath the Ross Ice Shelf stars in a recent popular webcast (see below). NASA scientists were using a borehole camera to look back up towards the ice surface when they spotted this pinkish-orange creature swimming beneath the ice.

Stacy Kim of Moss Landing Marine Laboratory was the first biologist to see the video and immediately recognized it as a Lyssianasid amphipod. It was about 3 inches long and Stacy concluded that this meant there was quite an extensive biological community under the ice here – even 20 miles from open water.

Snow Leopard Playing in the Snow in Ohio

While many people were getting tired of the massive snowfall over the last week others are having fun, including some animals having Snow fun at the Akron Zoo

Shanti, a 1-year-old snow leopard that took up residence at the Akron Zoo last fall, thinks the snowfall and subfreezing temperatures are great fun, said David Barnhardt, director of marketing and guest services.

”It may be one of her first snowfalls,” Barnhardt said of the youngster that came to the zoo from The Binder Park Zoo in Battle Creek, Mich. ”She’s literally doing back flips,” he said.
…
Also taking advantage of the snow and a respite from zoo visitors were red pandas, who thoroughly enjoyed playing outside, Barnhardt said.

My furnace chose the start of this snowfall, to break so I am surviving a few days without central heating. Doing so reminds me of the conveniences I take for granted – like being warm in the winter. It also makes me think that it would be nice to have fur like a snow leopard for a few days.

Crow Using a Sequence of Three Tools

This crow was the first animal observed using 3 tools in the correct sequence, without explicit training.

Bewick’s Swan Divorce

Experts stunned by swan ‘divorce’ at Slimbridge wetland

It is only the second time in more than 40 years that a “separation” has been recorded at the centre. Staff have described the new couplings as “bizarre”. It is not unheard of for the birds, which usually mate for life, to find a new mate but it tends to be because one of the pair has died, they said.

During the past four decades 4,000 pairs of Bewick’s swans have been studied at Slimbridge, with only one previous couple moving on to find new partners.
…
First suspicions of the rare event were raised when male swan Sarindi turned up in the annual migration from Arctic Russia without his partner of two years Saruni and with a new female – newly-named Sarind – in tow.

The pair’s arrival led conservationists to fear the worst for Saruni. But shortly afterwards Saruni arrived at the wetlands site – also with a new mate, Surune.
…
As for why they may have split, she said: “Failure to breed could be a possible reason, as they had been together for a couple of years but had never brought back a cygnet, but it is difficult to say for sure.”

Bewick’s swans are the smallest and rarest of the three species found in the UK and each individual can be identified by their unique bill pattern.

Unique Dolphin Strategy for Hunting Fish

A pod of bottle-nose dolphins off the coast of Florida have developed a hunting technique unknown in other dolphins. One swims in a circle stirring up mud and then the dolphins wait to catch fish that jump out of the water to escape the contracting circle of muddy water.

What Dogs Reveal About Evolution

From, The Greatest Show on Earth: The Evidence for Evolution by Richard Dawkins

All breeds of dogs are domesticated wolves: not jackals, not coyotes and not foxes.
…
Coppinger points out that when domestic animals break free and go feral for many generations, they usually revert to something close to their wild ancestor. We might expect feral dogs, therefore, to become rather wolf-like. But this doesn’t happen. Instead, dogs left to go feral seem to become the ubiquitous “village dogs” – “pye-dogs” – that hang around human settlements all over the Third World. This encourages Coppinger’s belief that the dogs on which human breeders finally went to work were wolves no longer. They had already changed themselves into dogs: village dogs, pye-dogs, perhaps dingos.

Real wolves are pack hunters. Village dogs are scavengers that frequent middens and rubbish dumps.
…
Belyaev and his colleagues (and successors, for the experimental programme continued after his death) subjected fox cubs to standardised tests in which an experimenter would offer a cub food by hand, while trying to stroke or fondle it. The cubs were classified into three classes. Class III cubs were those that fled from or bit the person. Class II cubs would allow themselves to be handled, but showed no positive responsiveness to the experimenters. Class I cubs, the tamest of all, positively approached the handlers, wagging their tails and whining. When the cubs grew up, the experimenters systematically bred only from this tamest class.

After a mere six generations of this selective breeding for tameness, the foxes had changed so much that the experimenters felt obliged to name a new category, the “domesticated elite” class, which were “eager to establish human contact, whimpering to attract attention and sniffing and licking experimenters like dogs.” At the beginning of the experiment, none of the foxes were in the elite class. After ten generations of breeding for tameness, 18 per cent were “elite”; after 20 generations, 35 per cent; and after 30 to 35 generations, “domesticated elite” individuals constituted between 70 and 80 per cent of the experimental population.
…
The tame foxes not only behaved like domestic dogs, they looked like them. They lost their foxy pelage and became piebald black and white, like Welsh collies. Their foxy prick ears were replaced by doggy floppy ears. Their tails turned up at the end like a dog’s, rather than down like a fox’s brush. The females came on heat every six months like a bitch, instead of every year like a vixen. According to Belyaev, they even sounded like dogs.

These dog-like features were side- effects. Belyaev and his team did not deliberately breed for them, only for tameness.

The famous domesticated silver fox experiment offers interesting insight into animal traits and evolution.
