How a facial recognition tool for bears can help manage wildlife

BearID uses deep learning, a subset of machine learning that makes use of artificial neural networks, to analyze images and identify individual bears.

When a grizzly bear attacked a group of fourth- and fifth-graders in western Canada in late November 2025, it sparked more than a rescue effort for the 11 people injured—four with severe injuries. Local authorities began trying to find the specific bear that was involved in order to relocate or euthanize it, depending on the results of their assessment.
