From the Summit Daily News (Julie Sutor):
At this time of year, bears are looking for new plant growth and fresh grass to eat to help them restart their digestive systems. But once they are up and running, bears are opportunistic feeders and will exploit any available food supply, including garbage, pet food, bird seed, and home and restaurant table scraps. Bears that become habituated to human food sources can be dangerous and often must be euthanized. Because they are large omnivores, bears are nearly always on a search for food. Wild foods are essential for bears — berries, insects, acorns, plants and carrion. But when people fail to store garbage, pet food or bird feeders properly, bears will find those sources and cause conflicts in residential and business areas. In Colorado, bears are ubiquitous from the Front Range across the Western Slope. Although sightings of grizzly bears are reported on rare occasion in the Centennial State, North American black bears (Ursus americanus) are the only bear species known to have established Colorado populations. Their preferred habitats are areas with aspen trees and oak brush.
More coverage from the Telluride Daily Planet (Kathrine Warren):
“We have a lot of bears moving around,” said Division of Wildlife Spokesman Joe Lewandowski. They’re on the move for food of any kind. These large omnivores usually eat new plant growth, fresh grass to help restart their digestive systems, berries, insects and acorn forbs. Lewandowski said the DOW wants to remind people that they’ll start wandering around looking for food of any kind, including trash.
