SPOONER, Wis. (AP) — State wildlife officials say animals face a new danger this summer: bird feeders.

The Department of Natural Resources says some feeders can accidentally kill other wildlife such as raccoons and skunks and even bear cubs.

The agency points to two cases in northwestern Wisconsin where bear cubs got their heads stuck in feeders while searching for food. In one case the cub's mother freed it. In the other, agency workers had to tranquilize the mother and cub and then remove the feeder.

DNR Wildlife Technician Robert Hanson says people shouldn't feed birds or any other animals during the summer. They know how to forage for themselves well enough.

If people insist on feeders, they should be on strong poles at least 8 feet high.
