“Willow: Diary of a Mountain Lion”

Aired Thursday 30 October 2025

A unique, non-invasive, mountain lion study uses a giant network of trail cameras scattered throughout Montana's Sapphire Mountains over a decade to piece together the lives of a female mountain lion called Willow and her kittens. This film weaves clips of mountain lions and their complex interactions with each other and the rest of the forest world into a story about life and death that contains never-before-captured events and behaviors at every turn.
