Wildlife managers have closed several areas this summer due to bear activity and to avoid unwanted encounters
FRISCO — After earlier summer closures of popular national forest areas due to close encounters with bears, Denver Water and Colorado Parks and Wildlife have decided to close Waterton Canyon to public recreation until further notice — for the same reason.
According to a release from Denver Water, there are two sows, each with twin cubs, and other bears actively foraging in the canyon. Friday afternoon, a biker was chased by a bear in the canyon. No one was injured. Continue reading

Biologists say noise impacts should be part of wildlife conservation planning
FRISCO — Outside a few remote wilderness areas, human-caused noise pollution is so common that birds have started to “shout” in order to communicate with each other.
Biologists with the University of Exeter took a close look at how bluebirds alter their songs in response to increases in nearby background noise caused, in many cases, by human activities such as traffic. Continue reading

UK study tracks impacts to coastal birds in Scotland
FRISCO — Biologists in the UK say stronger winds projected my many climate change models could have a big impact on some coastal bird populations. When winds are strong, females take much longer to find food compared with their male counterparts.
In many seabird species, females are smaller and lighter than males, and so must work harder to dive through turbulent water. They may not hold their breath for as long, fly so efficiently nor dive as deeply as males. The study suggests that climate change will exacerbate the differences and could ultimately affect population sizes.
To reach their findings, scientists with the Centre for Ecology & Hydrology at the University of Edinburgh and the British Antarctic Survey tracked shags — cormorant-like birds — on the Isle of May National Nature Reserve in south-east Scotland. Small tracking devices attached to the legs of birds helped measured how long they foraged for fish in the sea.
Scientists found that when coastal winds were strong or blowing towards the shore, females took much longer to find food compared with males. The difference in time spent foraging became more marked between the sexes when conditions worsened, suggesting that female birds are more likely to continue foraging even in the poorest conditions.

California wildlife agency documents five wolf pups and two adult wolves
By Bob Berwyn
FRISCO — OR-7, the lone wolf that enthralled wildlife lovers when he wandered through northern California a few years was the trailblazer.
Earlier this spring another lone wolf wandered into the state, and now, the California Department of Fish and Wildlife says there’s a new wolfpack forming. The agency has photographically documented five pups and several individual adults that have taken up residence in the state.
“This news is exciting for California,” said Charlton H. Bonham, CDFW Director. “We knew wolves would eventually return home to the state and it appears now is the time.” Continue reading

South Dakota a hot spot for wolf deaths
FRISCO — Since the Dakotas are sandwiched between Montana and Minnesota, it’s probably not completely surprising that wolves turn up there from time to time.
But the latest sighting of what certainly looks like a wolf has spurred a call for more education and public outreach to prevent the animal from being shot, either by accident or purposefully by over-eager hunters.
Other wolves have been shot been shot and killed in South Dakota in recent years, as reported by newspapers there, and the Center for Biological Diversity has also tracked the fate or wolves that wandered out of the northern Rockies. Continue reading

Lance Crosby was a 5-year seasonal resident of Yellowstone; park rangers say they will euthanize the bears responsible for the death
FRISCO — Yellowstone National Park officials have identified the 63-year-old man who was killed Aug. 7 by a grizzly bear. The victim was Lance Crosby, a long-time employee of Medcor, the company that operates three urgent care clinics in the park.
According to a park service press release, Crosby had worked and lived in Yellowstone for five seasons and was an experienced hiker. Park officials continue to investigate the death, with preliminary results showing that Crosby was attacked by at least one grizzly bear. His body was found partially consumed and cached, or covered, and partial tracks at the scene indicate that an adult female grizzly and at least one cub-of-the-year were present and likely involved in the attack.

More wolves may roam from Oregon into adjacent states, including California, where the state is developing a wolf management plan.
Conservation activists say sighting confirms need for endangered species protection
FRISCO — Wildlife biologists in California say another gray wolf has likely wandered into the far northeastern corner of the state. Based on an evaluation of photos and paw print measurements, the animal may be a lone dispersing male looking for new territory to occupy.
The California Department of Fish and Wildlife has deployed motion-sensor cameras and biologists will try to collect scat for a DNA sample to conclusively establish whether the observed canid is indeed a wolf. The sighting was in Siskiyou County, in an area comprised of both U.S. Forest Service holdings and private timberland. Continue reading
