Group Formation of New Isle Royale Wolves Leads to Territorial Aggression
December 20, 2019
GPS collar data shows three wolves, 1 female and 2 males, have been traveling, feeding, and bedding together since March, 2019 (W001F, W007M, and W013M). This is the first wolf group to form and remain associated since introduction efforts began... In October just prior to island closing, NPS staff came across the remains of male wolf, M183, one of the two remaining uncollared resident wolves inhabiting Isle Royale prior to introduction efforts. Necropsy revealed that M183 had been killed by another wolf or wolves.
