He sat in a hammock and camped in southeastern Colorado. Then, authorities say, a bear bit him.

A man camping near the Purgatoire River in Trinidad in southeastern Colorado was bitten by a bear Saturday night but is expected to survive.

Colorado Parks and Wildlife says the camper was resting in a hammock when he apparently startled a bear standing next to him.

The bear left a 2- to 3-inch wound in the man’s arm before wandering off, according to CPW.

“Bear attacks are rare and we take them very seriously,” said Mike Brown, CPW’s wildlife manager for the region. “We are doing everything we can to locate this bear. And we will continue to investigate the incident. Fortunately, the victim’s injury turned out to be relatively minor.”

If caught, the bear will be euthanized under CPW policy.

The camper, whom CPW officials did not publicly identify, said he heard rustling noises around 10 p.m. He turned on his headlight and then the bear bit him. The man went to a local motel and called an ambulance.

Now CPW and the US Department of Agriculture are searching the area with teams of trappers, inspectors and dogs. A trap was set up near the campsite where the bear bit the man, in case he returns.
