Girl Scouts who were attending camp nearby watched as the year-old bear was sedated and examined by Pennsylvania Game Commission officer Matthew Lucas, the Pittsburgh Tribune-Review reported.
Lucas called doughnuts a perfect enticement.
"Its sweet. Its greasy -- everything a bear loves," he said.
Lucas said the young bear had probably been chased off by its mother who was preparing for another breeding season.
The youngster will be taken to state game land and released, he said.
