Wildlife officers are studying the growing black bear population in the eastern part of the state, and they say they've had the best success in trapping the animals when they use pastries as bait.
Craig Endicott of the Wildlife Department told Tulsa television station KOTV the agency usually finds 300-pound male bears and 200-pound females in its traps. But on a recent day, a 50-pound cub got to the doughnut first.
The bears are tagged and researchers take fur and tissue samples for DNA analysis. Some adult bears get tracking collars.
Researchers also are setting up about 200 bait stations equipped with hair snares. DNA from the hair will help map bears' movement.
