Officials with the U.S. Fish and Wildlife Service are seeking information on a dead grizzly bear found on the west side of Hungry Horse Reservoir over the weekend.

According to a press release sent Tuesday by Montana Fish, Wildlife and Parks, the bear was reported to the state wildlife agency and wardens retrieved the grizzly.

Fish, Wildlife and Parks spokesman John Fraley said he couldn’t provide any additional information because the case is under active investigation.

Grizzly bears are a federally protected species in the lower 48 states under the Endangered Species Act.

Anyone with information on the incident is asked to call Brian Lake of the U.S. Fish and Wildlife Service at (406) 761-2286 or 1-800-TIP-MONT.

A reward is available to anyone reporting information leading to a conviction.

In other grizzly news, wildlife authorities shot and killed a female grizzly bear after she twice killed sheep on a ranch southeast of Valier.

Fish, Wildlife and Parks grizzly bear manager Mike Madel said federal wildlife officials shot the 6-year-old bear from a helicopter on Sunday as it was bedded down near the west shore of Lake Frances southwest of Valier.

The bear and two cubs were relocated to the North Fork of the Flathead River area last July after killing sheep on the ranch. The 350-pound bear returned this year, without her cubs, and killed more sheep.

Madel says wildlife officials have captured and relocated three grizzly bears along the Rocky Mountain Front this spring, while one grizzly was shot in self-defense east of Choteau.
