Larger Wolf Packs Less Successful in Hunting Elk

A few weeks ago Yellowstone National Park officials discovered the carcass of one of the park’s deadliest wolves, an aging male that scientists knew to be an aggressive bison hunter.

Wolf No. 495 died naturally, but his body bore bruises consistent with injuries inflicted in an encounter with large game, according to Dan MacNulty, an assistant professor of wildlife ecology at Utah State University.

The wounds found on No. 495 help explain MacNulty’s latest findings that wolves’ hunting success bears little correlation to the size of the hunting party beyond four wolves. Wolves hunt in groups because taking down large hoofed animals is not only challenging but dangerous.

But if the attack party exceeds four animals, the chance of success levels off, according to research MacNulty and colleagues published this week in the journal Behavioral Ecology.

Lone Wolf Goes the Distance

Somewhere in the rolling tundra east of Deadhorse, a lone wolf hunts. The 100-pound male will take anything it can catch, or find – a ptarmigan, a darting tundra rodent, a fish, the scraps of a carcass, or, if lucky, a moose calf or caribou. Hunger is a common companion, but the wolf somehow survived when his mate probably died of it last winter.

That event may have triggered the lone wolf’s incredible summer journey from south of the Yukon River to the crumbling shores of the Beaufort Sea. The wolf has traveled about 1,500 miles in four months, according to biologist John Burch, who works for the National Park Service.

Burch has studied wolves and the things wolves eat since the mid-1990s at Yukon-Charley Rivers National Preserve and Gates of the Arctic National Park and Preserve. Last November, he was part of a team that helicoptered to Copper Creek, a remote tributary of the clear-running Charley River. There, he tranquilized a healthy male wolf and fitted it with a satellite radio collar. The collar transmits GPS coordinates from the wolf every few days, which has allowed Burch to follow the wolf¹s trans-Alaska trek this summer.

Burch would have preferred that the wolf remain near Yukon-Charley, 2.5 million acres where the Yukon flows into Alaska. The wolf’s collar is expensive and would give useful information about one of a dozen wolf packs
that use the preserve as part of their home range. But the lone male is telling the biologists a different story about wolf behavior – what happens when a pack breaks up.

Wolf Recovery Leader Not Your Average Bureaucrat

Ed Bangs has long been a lightning rod for the controversy around the return of wolves to the U.S. Northern Rockies. Based in Helena, Mont., he led the U.S. Fish and Wildlife Service’s wolf-recovery effort from 1988, when the region had only a few naturally occurring wolves, through the reintroduction of Canadian wolves in 1995 and ’96, until his retirement in June 2011. During those years, the number of wolves in the region increased to more than 1,700. A plethora of lawsuits, alarmist headlines and political maneuvers culminated with Congress removing most of the region’s wolves from the Endangered Species List (an action also being challenged by lawsuits) just as Bangs retired.

Throughout the wolf battles, people on all sides of the issue respected Bangs for his unusual frankness and good humor. HCN’s senior editor, Ray Ring, talked with the 60-year-old biologist on July 1 about his lifelong interest in wildlife and his reflections on wolves and human society in general.

Keystone Species: How Predators Create Abundance and Stability

Long reviled as beasts of waste and desolation, wolves — along with other keystone predators — actually bring ecological stability to the habitats in which they live.

After an absence of half a century, wolves came back to Glacier during the 1980s, trotting across the border from neighboring Canadian wildlands. Suddenly, this Rocky Mountain landscape held more carcasses of deer, elk and moose, and those of us who frequented the slopes began to discover a few scavenging grizzlies later and later into the frozen season. One valley, with prime wintering grounds for hoofed herds, hosts a big male silvertip grizzly that I’m not sure ever holes up to snooze anymore.

Wolverines, with their unsurpassed nose for leftovers, can find more meals now as well. So can wintering bald eagles and golden eagles, along with northern ravens, which often follow wolf packs on the prowl. Wildlife biologists tracking the wolves discovered them taking over fresh kills made by mountain lions. In many cases, the packs seemed to be honing in on the sight of circling ravens or the birds’ excited calls in order to find the stealthy cats and drive them off their prize. Before wolves were reintroduced to Yellowstone National Park in the mid-1990s, cougars had expanded their range to include broad valley bottoms. After the wolves’ return, the cougars retreated to the steeper, more broken upland terrain they had normally hunted.

Scientists Debate ‘Magic Number’ of Wolves Needed for Species’ Survival

by Rob Chaney

One of the biggest arguments left unresolved by last year’s wolf lawsuit was the most obvious: How many wolves are enough?

The U.S. Fish and Wildlife Service took the gray wolf off the endangered species list in 2009, with the caveat that at least 150 wolves and 15 breeding pairs endure in each of the three states in the northern Rocky Mountain population (Montana, Idaho and Wyoming). Recent surveys found at least 1,700 wolves in that area – more than enough to justify delisting.

But a coalition of environmental groups sued the government, claiming those numbers were wrong. To survive and thrive, they argued, the population needed at least 2,000 and preferably 5,000 wolves.

FWS biologists said they used the best available science to pick their number. Coalition members cited the well-established rules of conservation biology to justify their threshold. While the scientists dueled, U.S. District Judge Donald Molloy decided the case on a technicality and Congress reversed him with a budget rider.

Wolves in the Northern Rockies are now delisted, but almost nobody’s happy.

Black Wolf Yields a Wild Hero

In the next few weeks—from May 7 through May 14—the 34th annual International Wildlife Film Festival screens 100 films that attempt to tell wildlife stories that are both entertaining and accurate. Among those, The Rise of Black Wolf is at the top, as a film that tells a good, solid story without resorting to melodrama. The Montana-made documentary, by Emmy Award-winner Bob Landis, follows almost the entire life of one wolf as he breaks from his pack and lives to be nine-and-a-half years old—one of the oldest wolves documented in Yellowstone National Park. This particular black wolf, known by scientists and wolf enthusiasts as Black Wolf, Casanova, and 302M, has been the protagonist in other Landis films, including In the Valley of the Wolves, and was monitored by the Yellowstone Wolf Project because of his unique behavior.

Lawsuit Challenges Constitutionality of Anti-Wolf Rider

Challenge Says Congress Illegally Lifted Wolf Protections in Northern Rockies, Pacific Northwest

The Center for Biological Diversity today filed a challenge in federal district court in Missoula, Mont., arguing that a congressional rider requiring removal of Endangered Species Act protections for wolves in the northern Rocky Mountains is unlawful because it violated the separation of powers in the U.S. Constitution. The rider was attached to last month’s must-pass federal budget bill by Sen. Jon Tester (D-Mont.) and Rep. Mike Simpson (R-Idaho) and marked the first time an animal or plant has been removed from the endangered species list by Congress.

“The wolf rider is a clear example of overreaching by Congress that resulted in the wrongful removal of protections for wolves,” said Noah Greenwald, endangered species director at the Center for Biological Diversity. “The rider is not only a disaster for wolves but for any endangered species that a politician doesn’t like. Congress has set a terrible precedent that we hope to overturn.”

Brisk Sales of Permits for Planned Idaho Wolf Hunts

by Laura Zuckerman

Permits for planned wolf hunts sold briskly in Idaho on Thursday, as most wolves in the Northern Rockies were officially removed from the endangered species list and conservationists sued over the unprecedented removal of protection by Congress.

The end of federal protection means that the roughly 1,200 wolves in Idaho and Montana will be managed by state wildlife agencies. The two states are seeking to kill hundreds of wolves, mostly through public hunting to begin in the fall.

Hunters were lining up in Idaho to purchase “tags” priced at $11.95 to help fill a hunting quota expected to be set at 220 of the state’s 700 wolves. Montana is likely to set the same quota for its 550 wolves.

Salazar Presents National Strategy for Wolf Recovery

by Rocky Barker

Interior Secretary Ken Salazar wasn’t satisfied Thursday with simply carrying out Congress’s mandate that he take gray wolves in the Rocky Mountains except for Wyoming off the endangered species list.

Salazar used the occasion to propose delisting in the Western Great Lakes and to unveil a national strategy for wolf recovery that wildlife groups have been pushing for many years. That strategy is bold and challenges the way many people have looked at the issue in the past.

The biggest change is that gray wolves that wander into 29 eastern states will no long be protected by the Endangered Species Act. The U.S. Fish and Wildlife Service’s scientists determined that gray wolves, canis lupus, never really lived there.

Instead, the agency will begin a status review of the wolf they say did live there, the canis lycaon or Eastern Canadian wolf. This smaller version is similar to red wolves that have been reintroduced to the Southeast. Some scientists say this subspecies used to live in Maine, the Adirondacks and even the Catskills famous for Borscht belt comedians like Henny Youngman who might have said, “take our wolves…please!”

Wyoming Elk Researchers to Give Talk About Study

by Perry Backus

Wyoming researchers looking for the cause behind declining pregnancy rates in a Yellowstone National Park elk herd will talk about their study this week in Hamilton.

Sponsored by the Ravalli County Fish and Game Association, the talk begins at 6 p.m. at the Bitterroot River Inn.

“When dealing with wildlife management, you can never have too much information,” said association president Tony Jones. “We’re hoping that some of the things they learned may transfer over to what’s happening here.”

Last winter, Montana Fish, Wildlife and Parks started an ambitious study in the Bitterroot Valley looking the relationship between elk and predators.

“Big game numbers here are doing the same thing that they’ve seen in Wyoming,” Jones said. “We want to get a better handle on why our big game numbers are on a fast decline … when you have wolves and lots of them, it’s easy to say they are the problem. Sometimes it’s not the wolf that’s doing the bulk of the damage.”

by The Associated Press

Montana officials are proposing to allow 220 gray wolves to be shot during the state’s second wolf hunting season this fall.

The figure is the highest proposed quota yet in the state — up from 186 in the canceled 2010 season and 75 in the inaugural wolf hunting season in 2009. The Independent Record in Helena reports Montana Fish, Wildlife and Parks officials say the new quota will result in a 25 percent reduction from the estimated 2010 population of 566 wolves in the state.
