Bear Hibernates in Family's Cabin

A Washington state woman was in for a big surprise when she arrived at her family's Montana vacation cabin: It was ransacked, and the family's belongings were strewn everywhere.

"My sister went up for New Year's and thought someone had broken into the cabin," Molly Reynolds told ABC News affiliate KXLY4 in Spokane, Wash.

She realized nothing was taken, but something was definitely there that shouldn't have been: a hibernating black bear that has made the home his own for the season.

Family members were in for an even bigger surprise when they realized the bear had stripped the pillows and a blanket from one of the beds.

After inspecting the cabin, Reynolds' uncle found a small, broken trap door leading to the crawl space between the home and the ground. Once he went inside he saw two bright eyes staring back at him.

"We had a bear crawl up through the crawl space of our cabin and he took out some pillows and some bedding and took it back underneath the cabin," Molly Reynolds told KXLY4. "I thought that was a comfortable place for him with the bedding and he's been there ever since."

Reynolds refused to have the bear moved.

"We told [wildlife officials] that we didn't want to disrupt the bear or have him hurt in any way," Reynolds told ABC affiliate KXLY4. "We don't use the cabin right now, so we didn't feel there was the need to get him out."

They even nicknamed the sleeping bear Blue. From the looks of it, the bear seemed rather large, so the Reynoldses hope when they go back to their cabin, a family of bears won't be waiting.

"We wondered if there were going to be little babies, but I don't know that yet," Reynolds told ABC affiliate KXLY4.

Creatures caught in the act

Motion-activated remote cameras are capturing images of wildlife throughout the southern Rockies of Alberta and B.C. and researchers hope they give them some answers on wildlife behaviour, movement and distribution over a large landscape.

With no one actually behind remote battery-operated cameras, these images offer a rare and privileged view of wild animals going about their everyday lives. Every time something passes the camera’s infrared beam, an image is taken.

This year marks the third year of the remote camera wildlife monitoring program in Banff, but it’s now being extended to include Jasper, Waterton Lakes, Yoho and Kootenay national parks, as well as provincial lands in Kananaskis Country.

Wildlife officials say they are excited about the multi-jurisdictional pilot project because they can potentially use this non-invasive and relatively low cost method to monitor several wildlife species and human use across a study area of more than 40,000 square kilometres.

“We realized we were all putting out remote cameras for different reasons and not working together at all and so we all got together to work collaboratively,” said Jesse Whittington, a wildlife biologist for Banff National Park.

“This is super exciting because it will give us a lot more power to determine how wildlife populations are changing. Remote cameras are increasingly being used to monitor species diversity around the world.”

Approximately 42 motion-activated cameras are mounted on trees or encased in rock cairns along hiking and game trails throughout the 6,500 square-kilometre Banff National Park.

The larger-scale project has 40 cameras in Jasper, 20 in Yoho and Kootenay and about 40 in Waterton Lakes. There are also about 20 cameras on provincial lands in Kananaskis Country.

All parks are involved with setting up and servicing cameras, classifying photos, and participating in discussions on how to proceed with analysis and future sampling.

Robin Steenweg, from the University of Montana, will analyse the data and come up with recommendations on the best sampling protocols to use and will conduct large-scale analysis on factors affecting species distributions.

While the power of remote cameras lies in their ability to capture images from all species, this project is primarily interested in grizzly bears (including the number of females with cubs), wolverines and lynx, which are struggling in parts of the United States, and of which little is known here.

Researchers also want to keep a close eye on species such as white-tailed deer, which could have potential wolf-mediated effects on caribou, and keep an eye on levels of human use on trails.

So far, the cameras have recorded grizzly bears on 39 of the 42 cameras in Banff National Park, discovered wolverines are concentrating in the Cascade area and that lynx are scattered throughout the park.

Parks Canada officials say they have been particularly surprised by the number of fox photos in Banff, noting very few staff have ever seen one in Banff National Park, which is a testament to the fox’s nocturnal and wily nature.

Whittington said Parks Canada recently finished processing 130,000 images taken over the course of last summer.

He said the cameras captured a family of three wolverines going over a pass in the south end of Banff National Park and recorded at least four grizzly bears using a rub tree in the Cascade area.

But what Whittington found most interesting is that the Fairholme benchlands in the Bow Valley are proving to be a “huge hot spot for wildlife activity,” noting there were several grizzlies using the area last summer.

“We have a female grizzly with a cub that we didn’t know about, and the Fairholme wolf pack denned up on the bench and had at least six pups, which we also didn’t know about,” he said.

“The Fairholme is one of most productive habitats in Banff and it’s great to see it’s teeming in wildlife… this kind of information is always fascinating. There’s some really neat stuff.”

Whittington said researchers have been surprised at how well the remote cameras have worked for wolf monitoring, given wolf packs are very dynamic and their numbers and range can change considerably each year.

“The cameras work well because we can determine the minimum number and colours of wolves within each area and from that we can piece together how many wolves are in each wolf pack,” he said.

“Wolf density and distribution are very important to monitor because wolves can have large top-down effects directly on prey species, such as elk, and secondary effects on vegetation and song-bird communities.”

Whittington said, similarly, wolf density can have large effects on caribou survival, which is important given Parks Canada is working towards a caribou translocation program in Jasper and/or Banff through captive rearing.

He said most caribou herds require wolf densities of less than six wolves per 1,000 square kilometres.

“For the last four years, we’ve had between two and three wolves per 1,000 square kilometres, which makes us think that conditions should be better for caribou survival,” he said.

“Caribou survival also depends on how much time wolves spend in caribou range, which recently has been high.”

Whittington said the cameras also pick up human use activity, noting hardly any people were recorded going into the voluntary closure on the Fairholme bench at all, with the exception of Carrot Creek.

He said the cameras may also help Parks monitor human use in the backcountry.

“Knowing how many people use the backcountry in Banff will help us determine where to concentrate efforts for maintaining backcountry trails and how human use in the backcountry may be affecting wildlife,” he said.

Snowy owls soar south from Arctic in rare mass migration


SALMON, Idaho (Reuters) - Bird enthusiasts are reporting rising numbers of snowy owls from the Arctic winging into the lower 48 states this winter in a mass southern migration that a leading owl researcher called "unbelievable."

Thousands of the snow-white birds, which stand 2 feet tall with 5-foot wingspans, have been spotted from coast to coast, feeding in farmlands in Idaho, roosting on rooftops in Montana, gliding over golf courses in Missouri and soaring over shorelines in Massachusetts.

A certain number of the iconic owls fly south from their Arctic breeding grounds each winter but rarely do so many venture so far away even amid large-scale, periodic southern migrations known as irruptions.

"What we're seeing now -- it's unbelievable," said Denver Holt, head of the Owl Research Institute in Montana.

"This is the most significant wildlife event in decades," added Holt, who has studied snowy owls in their Arctic tundra ecosystem for two decades.

Holt and other owl experts say the phenomenon is likely linked to lemmings, a rodent that accounts for 90 percent of the diet of snowy owls during breeding months that stretch from May into September. The largely nocturnal birds also prey on a host of other animals, from voles to geese.

An especially plentiful supply of lemmings last season likely led to a population boom among owls that resulted in each breeding pair hatching as many as seven offspring. That compares to a typical clutch size of no more than two, Holt said.

Greater competition this year for food in the Far North by the booming bird population may have then driven mostly younger, male owls much farther south than normal.

Research on the animals is scarce because of the remoteness and extreme conditions of the terrain the owls occupy, including northern Russia and Scandinavia, he said.

The surge in snowy owl sightings has brought birders flocking from Texas, Arizona and Utah to the Northern Rockies and Pacific Northwest, pouring tourist dollars into local economies and crowding parks and wildlife areas. The irruption has triggered widespread public fascination that appears to span ages and interests.

"For the last couple months, every other visitor asks if we've seen a snowy owl today," said Frances Tanaka, a volunteer for the Nisqually National Wildlife Refuge northeast of Olympia, Washington.

But accounts of emaciated owls at some sites -- including a food-starved bird that dropped dead in a farmer's field in Wisconsin -- suggest the migration has a darker side. And Holt said an owl that landed at an airport in Hawaii in November was shot and killed to avoid collisions with planes.

He said snowy owl populations are believed to be in an overall decline, possibly because a changing climate has lessened the abundance of vegetation like grasses that lemmings rely on.

This winter's snowy owl outbreak, with multiple sightings as far south as Oklahoma, remains largely a mystery of nature.

"There's a lot of speculation. As far as hard evidence, we really don't know," Holt said.

Did you know cheetahs ride shotgun?



The Cincinnati Zoo has a traveling version of its Cat Ambassador Program where zoo trainers bring a cheetah and several "smaller" cats to local schools. And that means road trips. But not in a cage. Nope. When these cheetahs go out on the town, they ride shotgun.

This is Sara, who became the fastest animal on earth back in 2009, breaking the 100 meter sprint record at 6.13 seconds. To put that in perspective, Usain Bolt's official human record is a languid 9.58 seconds.

World record holders aren't the only ones who get to ride in the zoo's Subaru Forester. Below, find a photo of another cheetah named Nia — who was just a year old when the picture was taken — as she looks out at Cincinnati.

Are we the only ones who think it's weird that a program requiring the disclaimer of "Due to the nature of wild cats, students will not be permitted to touch animals" probably shouldn't be running said wild cats around town in the front seat of a car? Sure, we've seen this type of thing before, but that was Dubai — not Ohio.

What if there's an accident? Or what if someone sees the cat in the front seat and, you know, flips the hell out?

So is this legal? Although we know Ohio has pretty lax laws on exotic animals we know that it may be illegal to do so on the Ohio Turnpike thanks to Section 5537-3-01 of the pay-for-use road's rules. The section concerns limitations on use of the turnpike and clearly states: "Vehicles transporting animals or poultry not properly secured or confined." We're assuming that could mean the front seat.

Of course, Cincinnati is nowhere near the turnpike and otherwise it appears Ohio's statutes are silent on the subject. But this is Ohio we're talking about — so we're just impressed they have laws of any sort.

Rare Sea Creature Appears on Seattle Woman's Dock


A Seattle resident recently got a big surprise when she discovered a strange-looking furry visitor on her property.

"She woke up and it was lying on her dock, hanging out and sleeping — just chilling," said Matthew Cleland, district supervisor in western Washington for the USDA's Wildlife Services, and the recipient of a photo of the bizarre intruder.

"I thought, 'That's an interesting-looking creature,'" Cleland told OurAmazingPlanet. "I had no idea what it was."

A quick glance through a book in his office soon revealed it was a ribbon seal, an Arctic species that spends most of its life at sea, swimming the frigid waters off Alaska and Russia.

Somehow, the seal turned up on the woman's property, about a mile from the mouth of the Duwamish River, a highly industrialized waterway that cuts through southern Seattle. In 2001, the EPA declared the last 5.5 miles (9 kilometers) of the river a Superfund site — an area contaminated with hazardous substances in need of cleanup.

The sighting was "pretty exciting," said Arctic seal researcher Peter Boveng, leader of the National Marine Mammal Laboratory's Polar Ecosystems Program. "It's really unusual."

Ribbon seals, named for the unmistakable stark white markings that ring their necks, flippers and hindquarters, typically shun dry land.

Boveng said the animals spend only a few months per year on sea ice, to molt and give birth, and have almost never been seen so far south. "So it's a surprise, but knowing the species, it's not a complete surprise to me," he said. "They're good travelers."

The ribbon seal, which Boveng identified as an adult male, "looked to be in really good shape," he said. "We don't have any way to rule out other possibilities, but I'd say it's almost certain that it swam there."

Satellite tracking studies have revealed that ribbon seals do sometimes make it as far as the north Pacific Ocean, south of the Aleutian islands, but much about the species remains mysterious. Because they spend so much of their lives in the open water, it's a challenge to track them.

"Unfortunately we don't know a lot about their numbers," Boveng said. "There's never been a reliable survey."

A conservation groups has made efforts to list ribbon seals as an endangered species because of concerns about disappearing sea ice in the Arctic. So far the federal government has declined to do so, but is continuing to review the case for listing.

The Seattle ribbon seal appears to be only the second on record to make it so far south.

In 1962, a ribbon seal showed up on a beach near Morro Bay, Calif., a town about 200 miles (320 kilometers) north of Los Angeles. According to contemporary reports, the seal was in good shape, but totally bald except for hair on the head, neck and flippers. It died a month later at the local aquarium.

The Seattle ribbon seal's story is unknown, but one could be forgiven for thinking it a harbinger of things to come. This week, cold winds from Alaska helped create a record winter storm in Seattle, slamming the metro area with 4 to 8 inches (10 to 20 centimeters) of snow.

The ribbon seal hasn't been seen again since it was first spotted last week.

"It stirred up a lot of interest," Cleland said. "There are a lot of people out here looking for it."

Monkey long believed extinct found in Indonesia



Scientists working in the dense jungles of Indonesia have "rediscovered" a large, gray monkey so rare it was believed by many to be extinct.

They were all the more baffled to find the Miller's Grizzled Langur — its black face framed by a fluffy, Dracula-esque white collar — in an area well outside its previously recorded home range.

The team set up camera traps in the Wehea Forest on the eastern tip of Borneo island in June, hoping to captures images of clouded leopards, orangutans and other wildlife known to congregate at several mineral salt licks.

The pictures that came back caught them all by surprise: groups of monkeys none had ever seen.

With virtually no photographs of the grizzled langurs in existence, it at first was a challenge to confirm their suspicions, said Brent Loken, a Ph.D. student at Simon Fraser University in Canada, and one of the lead researchers.

The only images out there were museum sketches.

"We were all pretty ecstatic, the fact that, wow, this monkey still lives, and also that it's in Wehea," said Loken.

The monkey, which has hooded eyes and a pinkish nose and lips, once roamed the northeastern part of Borneo, as well as the islands of Sumatra and Java and the Thai-Malay peninsula. But concerns were voiced several years ago that they may be extinct.

Forests where the monkeys once lived had been destroyed by fires, human encroachment and conversion of land for agriculture and mining and an extensive field survey in 2005 turned up empty.

"For me the discovery of this monkey is representative of so many species in Indonesia," Loken told The Associated Press by telephone.

"There are so many animals we know so little about and their home ranges are disappearing so quickly," he said. "It feels like a lot of these animals are going to quickly enter extinction."

The next step will be returning to the 90,000 acre (38,000 hectare) forest to try to find out how many grizzly langurs there are, according to the team of local and international scientists, who published their findings in the American Journal of Primatology on Friday.

They appear in more than 4,000 images captured over a two-month period, said Loken, but it's possible one or two families kept returning.

"We are trying to find out all we can," he said. "But it really feels like a race against time."

Experts not involved in the study were hugely encouraged.

"It's indeed a highly enigmatic species," said Erik Meijaard, a conservation scientist who spent more than eight years doing field research in the area.

In the past they were hunted to near extinction for their meat and bezoar "stones," he said, which can, on occasion, be found in their guts.

Bezoars, as Harry Potter fans know from lectures given by Prof. Snape to first year students, are believed by some to neutralize poison.

Meijaard said the animal has long been considered a subspecies of the Hose's Leaf Monkey, which also occurs on the Malaysian side of Borneo, but it now looks like that may not be the case.

"We think it might actually be a distinct species," he said, "which would make the Wehea discovery even more important."
