Rise in bear sightings expected as 'fall shuffle' gets underway – Yahoo News

As temperatures start the annual autumnal plunge, wildlife experts predict bears will start becoming more active and venture closer to humans.
Biologists refer to the animal’s increased mobility to find food as the ‘fall shuffle.’
The preparation for the winter can begin as early as August and last until food starts to become sparse, closer to the winter months.
Chris Servheen, a wildlife biologist, who previously served as the U.S. Fish and Wildlife Service's national grizzly bear recovery coordinator, said the weather’s impact on food sources effects when the animals start the trek to their winter den.
"The weather either helps kill off or helps increase the food availability, and that’s why bears either hibernate or don’t, Servheen said.
Servheen believes warm weather cannot only prolong how long bears forage for food, it can also speed up their return from the den in the spring.
"Adult bears need to take in approximately 20,000 calories a day during the fall," said David Telesco, Florida’s bear management program coordinator. "If given the opportunity, bears will take advantage of easy meals from things including unsecured trash cans and bird feeders. However, if bears don’t find a food source in a neighborhood, they’ll move on."
Biologists estimate there are around a million bears that roam the landscape of North America.
While encountering a bear is still considered rare in many parts of the country, Servheen believes human migration is leading to increase sightings.
"We see more and more people moving into their habitats now. And what that means is that there's more conflicts with bears because people are building houses and places where there are never houses before," Servheen said.
The National Park Service warns people should keep their distance and stay calm if they encounter a bear. The agency suggests knowing several tips if you ever come face-to-face with a bear:
