WILDLIFE -- Research underway in Washington, Oregon and Idaho seeks to understand more about a wilderness icon, North America's reclusive carnivore -- the wolverine.

Last weekend we took a glimpse at how citizen scientists are helping Idaho Fish and Game monitor a range of carnivores including wolverines in the Idaho Panhandle.

KING 5 TV  this week has an excellent update (above) on wolverine research in the North Cascades, including footage of a a fiesty critter trapped, collared and released.
