The wolf that researchers called 832F, left, was shot on Thursday. The alpha female of the Lamar Canyon pack, she wore a tracking collar. The wolf with her, known as 754, was killed last month.
The wolf, known as 832F to researchers, was the alpha female of the parks highly visible Lamar Canyon pack and had become so well known that some wildlife watchers referred to her as a rock star. The animal had been a tourist favorite for most of the past six years.
The wolf was fitted with a $4,000 collar with GPS tracking technology, which is being returned, said Daniel Stahler, a project director for Yellowstones wolf program. Based on data from the wolfs collar, researchers knew that her pack rarely ventured outside the park, and then only for brief periods, Dr. Stahler said.
