Kermode Bear


In a rainy autumn morning on the coast of British Columbia, a dark wood figure of the coast. A black bear came to eat. This is the spawning season. Eggs heavy abundance of fish in streams Gribbell Island, a small portion of the Great Bear Rainforest in Canada, one of the largest coastal temperate forests of the world. The bear stopped in a patch of seaweed algae to sniff the air. Rain and fog can not hide the funky putrefaction. The bodies of pink salmon and chum salmon are caught in the strands of linguine wave sedges. The bear moves like a silhouette in the landscape, its mixture of black hair with dark woods and dark stones.

Marven Robinson points bear, but away, indifferent. "We could have a better chance upstream" he said. Robinson, 43, robust and wrapped in rain gear, is a guide to wildlife and member of the Gitga'at First Nation whose traditional territory includes Gribbell Island. This bear is not what you want. It is after a most revered and rare creature called Gitga'at mooksgm'ol, Spirit of the Bear, a contradiction, a walking black polar bear.

Neither an albino polar bear and the spirit of the bear (also known as the Kermode Bear) is a variant of the white North American black bear, and was found almost exclusively here in the Great Bear Rainforest. At 25 000 square miles and a half times the size of Switzerland, passes through the area at a depth of 250 km on the west coast of Canada and includes a vast network of mist-shrouded fjords, forested islands, glacier-capped mountains and . Grizzly bears, blacks, wolves, wolverines, humpback and killer whales thrive along the coast that is home to First Nations as Gitga'at hundreds of generations. It is a scary, wild, mysterious place: there are wolves here in the fish. Deer that swim. Western Red Cedar trees have lasted 1000 years or more. And black bear, which is white.

As his boots making a wet track full of ferns and devil's club, Robinson looks for movement. There is no door. He sees a white patch of hair that hangs from a branch of alder. "They are here again," he said. Emphasis is placed on the bark chewed. "They like to bite the tree bears only say, I'm here with the river."

An hour passes. Robinson, waiting patiently for the Moss-patched boulder. Then he saw a rustle in the bush. "Here," he says.

White Bear lateral distance from the trees on the Rock Stream. Faced with a dark palette of tropical forests will unfairly bear fur radiation. Not pure white, exactly. More than a vanilla-colored carpets need steam cleaning. The bear's head swings from side to side, peering into the vortex of salmon. Before he can hit one, black bear suddenly out of the forest and passes through the polar bear off its perch, even if the "end" might be a bit 'strong. All the bears did not seem to take place in slow motion, as if they were trying to save every last calorie in the coming winter. White Bear lumbers into the bushes and disappear.

Robinson watches. He spent 15 years with the Spirit Bear. However, he nailed. "The polar bear is very particular subject," he said. "Sometimes it happens to me. I'm protective. I once saw an old polar bear attacked by a young black bear. I was about jump in and spray with black pepper. instinct was strong in me. But then the white reared and threw him out. "Robinson smiled, as if to admit the absurdity of a man jumping into a battle of bears. But in his eyes there is a hint that he might have done.

Robinson is not alone. The same protective instinct is strong in all the jungle of the Great Bear. This is one of the factors that have kept alive the spirit of giving.

"Our people have never hunted the polar bear," said Helen Clifton, who is sitting in her kitchen in Hartley Bay, a small fishing village dominated by tendrils of wood smoke and crows echo invocation. With voice and mind, Clifton 86 years is a matriarch of the clan of Gitga'at, one of 14 bands that constitute the Tsimshian people of the northwest coast of British Columbia. Bear Meat was rarely a staple food, she said. But First Nations hunters went after the black bear in a more European merchants established when the fur trade in British Columbia during the late 18 century. Even in those days but take a polar bear was a taboo subject, a tradition that continued for many generations. "We never spoke of the Spirit Bear at the table," said Clifton.

This tight-lipped the custom would have been an early form of environmental protection. Speaking of a bear, not to mention hunting, Gitga'at and adjacent frequency bands will never be the creature word reaches the ears, fur traders. Today Gitga'at and Kitasoo / Xai 'xais people keep an eye on their door during the hunting season. "It's no good to come when the black bear in our region," says Robinson. "You never know. We are able to shoot the bears back."

This attitude makes all the difference. For decades, the presence of poachers and trophy hunters, as well as mills and canning factory-built Great Bear Grizzlies rare and nervous. Industries have disappeared, as hunting grizzlies in some parts of the rainforest. The bear reacts. "In my first year was really something to see a grizzly bear," said Doug Stewart. As the patrol fishing agreement, Stewart followed the fish runs in Big Bear for over 35 years. "Now you see all the time. I can come through the five Grizzlies in one morning. "

They are so good, in fact, that some wonder if the return of the grizzly bear is not growing black and some white, against the best seasons for fishing in rivers. "When you see a Griz, you can not see a black bear or white," says Doug Neasloss a Kitasoo / Xai 'xais wildlife guide. "Black has Griz give much space."

This leads to an interesting possibility: Maybe the Griz had a hand in focus in the gene Kermode Gribbell Princess Royal and the islands. "Grizzlies and black bears live everywhere except on small islands," said Thomas Reimchen, a biologist at the University of Victoria. "There is not enough habitat for grizzly bears in these small islands. They need large estuaries grass, alpine habitat, and a wide range of home, including the islands do not."

The islands offer something else: human eyes watching over them. "I tell young people," said Helen Clifton, "When you see a bear spirit, not in the VHF and television. If you tell someone, say they saw mooksgm'ol. I know what you mean. And it will keep the door securely. "

Scientists know how black bears are born white. They just do not know why. This phenomenon, known as Kermodism is caused by a recessive mutation in the MC1R gene, the same gene are associated with red hair and fair skin in humans. Being born white, then a bear will inherit the mutation from both parents. The parents themselves should not be white. They just need to carry the recessive mutation. So it is not uncommon for polar bears to be born to black parents.

White fur occurs in one of every 40-100 bears blacks is the coast of British Columbia, but the section is particularly pronounced in some islands of the Great Bear Rainforest. Are the Princess Royal Island, one in ten blacks bears are white. And 'Gribbell Island, north of the Princess Royal, is one of the three. Biologist Wayne McCrory is Valhalla Wilderness Society, called Gribbell, "the mother of the 'island of white bears."

It is unclear how these features arose. A theory was "Bear Glacier" assumption that an adjustment residual Kermodism the last great ice age that ended 11,000 years ago. At that time, most of British Columbia today was still frozen and a white coat may have provided camouflage. But the theory of wear glacial raised a question: Why not the white coat features die when the glaciers retreated?

For more information, Neasloss Doug and I will find bears on Princess Royal Island. "Hey, bear," said Neasloss as jumping from a boat near the mouth of a small river. It is as if he had been a friend named Bear, but there are no animals in sight. "I'm not scared," said the guide 28, who works in the traditional territory of xais Kitasoo / Xai. A can of pepper spray grizzly force is based on a holster on his hip. Barnacle encrusted rocks through the clear parts and Neasloss the curtain of rain forest. Under the canopy as it rotates smoothly and silently. Lichen drops of hemlock, cedar, yew branches. His rubber boots leave no mark on the spongy soil, which is so green it seems that the sky dropped a foam snow.

Neasloss claiming a place under a tree, hemlock and pulls his hood tight against the incessant rain. He saw a polar bear near here recently, he said, but there is no guarantee it will reemerge. In just over three, he noted in the River. A white bear waddles down the bank. This bear is larger and safer than the bear Grip Bell Island. Fat rolls her belly. It seems to be a coat two sizes too big. It is perched on a small pool, slots, and with both feet and find a companion three-foot salmon chubby.

Researchers have recently shown that the spirit bear white coat gives you an advantage when fishing. Although polar bears and black tend to have the same success rate at night when the Bears make a lot of fishing and scientific Reimchen Dan Klink University of Victoria has noticed a difference in the day. The polar bear catch salmon in their third attempts. The only time blacks have achieved room. "Salmon are less concerned about a white object, seen from below the surface," speculates Reimchen. In part, this may answer the question of why white skin continues to grow today. If the salmon is a coastal bear primary fat source of protein and a successful woman can enjoy the salmon to store more fat for the winter, which could increase the number of puppies they can produce.

As the rain continues to fall Princess Royal Island, and I feel the spirit Neasloss bear eating salmon goodness. When the gains are so good, the Bears can turn a fussy eater. Some people only eat the fish head. Others may cut the belly and sucks cock. Some people are greedy. "Once I saw the spirit of the 80 bear eating salmon in one sitting," says Neasloss. This bear wants to dine privately. Rotate the teeth and the salmon runs straight uphill, hidden somewhere unseen. Twenty minutes later, the return of the bear, fish NABS seconds, and brings them into the woods. This goes for hours, until the daylight fades from the sky.

Egret Feathers


In the 1900s, was the great egret is snow white plumage in great demand to adorn women's hats and fashion. As a result, North American populations decimated by hunting birds - some groups with 95 percent. But over the last century, great egrets were under legal protection and their populations recover. According to the National Audubon Society, great egrets a world population of over 1 million people.

Heron - also called the great egret and great egret - are migratory birds with a wide distribution and, at present, the IUCN Red List classifies the Great White Egret as "least concern". Great Egret Although the species no longer suffer from intense hunting for trade in feathers, other threats. These water birds are vulnerable to loss of wetland habitats, climate change and invasion by exotic plants.


At the beginning of the breeding season, growth of flashy Egret feathers (called egrets), and they raise the fan in rituals of seduction. The shadow of their bills to brighten yellow to orange-yellow skin near their eyes are bright green.

One of the largest species of herons, great blue heron is growing at about three meters high and has a wingspan of more than four feet. Her long thin legs, birds with a characteristic S-shaped neck. Great egrets stalk their prey slowly - such as frogs, insects, small mammals and fish - for hunting in shallow wetlands.

Amazon Horned Frogs Can Reach The Size Of A Small Plate.


The first thing you notice about the Amazon horned frog is its size. These amphibians can grow round 8-inch (20 cm) in length and cover a dish of tea of ​​good size. They are found in freshwater marshes and pools throughout the Amazon basin, Colombia, Brazil.

Amazon horned frogs reach their enormous size, being generally indiscriminate about what they eat. Typical ambush predators, they squeeze their bodies into the forest floor or fallen leaves, leaving only the head showing. When nothing less than their own bodies happens by, they result from the mud and swallow their prey whole, lock their jaws with their sharp teeth.

They are aggressively territorial and voracious an error. Some were found dead in the wild with the remains of a victim unable to play still protruding from their mouths. Their voracious appetite and has earned enormous mouth and other horned frogs commercial PET nickname "Pac Man frogs."

Females are generally larger than males, but males are more richly colored, ranging from dark green to lime colored. Females are usually tan. Researchers are unsure what purpose their namesake horns serve, but it is likely that the assistance they dressed in camouflage, resembling leaf stems in the wild.

Squid "exceptional" Dying Giant Found Off Florida


Float about 12 miles (19 km) from Port Salerno (map), in Florida, stirring occasionally, intact giant squid on a small fishing village party shaken at 11 am Sunday and could give researchers new insights into the species, which is not never been studied in life, researchers say.

"We looked at it [and] all three were like, Holy Mackerel!" Benz Robby recreational fisherman told WPTV. "Do not you feel that was long dead, the tentacles were moving was closed when we arrived the" fishing boat.

After reaching the shore, the men called the wildlife authorities and the giant squid, and then died quickly found a home in the Florida Museum of Natural History in Gainesville.

The giant squid, the largest invertebrate in the world, is believed to reach lengths of up to about 60 feet (18 meters) and weighs almost tons. Florida individual, even if it is about 25 feet (8 meters) long and weighs about 200 pounds (90 kilograms).

Like other giant squid is the capture of new white with red spots on the skin that contains chromatophores, pigment-containing cells that can change color rapidly, probably for communication or camouflage.

Squid "Very Rare"

Giant squid in the oceans worldwide, but the animals were rarely spotted in the Atlantic off the coast of Florida, said Roger Portell, a paleontologist at the Museum of Invertebrate Natural History, which helps preserve the octopus.

"These are very rare animals," says National Geographic News Portell. "They tend to be in very deep water, so you do not normally see."

The new test, he added, is "extraordinary".

"There was very little trauma," he said. Although missing tentacle, squid does not seem to have been attacked, he added.

Although no marine animals, were once described, the giant squid have been known to fight deep in the sperm whales.

Like the giant squid seems to have been damaged even die, when it was found, Portela thinks of a new sample, sex is still unknown, may not be reproduced.

"Normally in cephalopods," including squid, octopus, cuttlefish and "two males and females die shortly after reproduction. We assume that this is what happens in this case."

Fishermen, he added, had the merit of a rare condition of the model, he added.

"I'm drawn away, and brought him to shore immediately, and urged the authorities, who put it on ice immediately. So it worked very well," Portela said.

Benz, Fisher said he was motivated to take part in massive prisoner, because he does not think anyone would believe him if he had not.

"Nobody believes a fisherman," he told WPTV.

Recorded giant squid body to science

At the museum, the model is injected with a preservative called formalin and are soaking in a chemical solution. (Photos: "giant squid Get Extreme plastic surgery.")

After two weeks of storage is complete, the squid will become part of the museum's research collection. The genetic data should be of particular interest to researchers trying to find the beast is called the giant squid Architeuthis DUX is actually more than one species, Portela said.

"We've had some researchers to call us down to watch it," he said.
