Another wolf DIES while being COLLARED - Should we stop Collaring Wolves?

A gray wolf being captured for research in Colorado has died after suffering extreme physiological stress during a tagging operation, according to the latest necropsy findings reported by 9News. The wolf — a three-year-old male known as 2305 from the King Mountain Pack — died on January 28, 2026, while wildlife staff attempted to recapture him to replace the battery in his GPS tracking collar. The procedure was carried out by Colorado Parks and Wildlife as part of the state’s wolf monitoring programme, which uses collars to track wolf movements, pack formation and interactions with livestock. But the necropsy has now revealed the wolf died from acute cardiogenic shock — a sudden failure of the cardiovascular system triggered by extreme stress. Reports state the wolf was darted and pursued for several minutes before immobilisation took effect. When the animal was reached, his body temperature had risen to 105.8°F (41°C) — a level consistent with severe overheating and metabolic stress. Shortly afterwards, the wolf stopped breathing and lost his pulse. Veterinarians attempted CPR and emergency drugs for around 20 minutes, but he could not be revived. Examination also found signs consistent with capture myopathy, a condition documented in wildlife biology where intense stress and exertion can cause muscle breakdown, overheating and cardiac failure in wild animals. GPS collars have become a major tool in modern wildlife science, helping researchers understand wolf territories, dispersal and predator–livestock conflict. But even under controlled conditions, capturing and immobilising wild animals carries known risks, particularly for highly stress-sensitive species like wolves. This wolf’s death now raises an uncomfortable question for wildlife science: If studying wolves requires chasing, darting and restraining them — procedures that can cause fatal stress — is ongoing collaring ethically justified, or is it time to find less invasive ways to study the animals we are trying to protect? .
