Capercaillie are at crisis point in Scotland with fewer than 500 individuals remaining, and recreational disturbance during winter is a direct welfare and population-level threat.
Capercaillie face a population-level welfare crisis driven partly by recreational disturbance. Each winter flushing event burns energy that capercaillie can ill afford — they survive cold Scottish winters on a diet of pine needles with minimal energy surplus. Repeated disturbance from walkers and dogs pushes birds into energy deficit, reducing survival and breeding condition. Disturbance avoidance zones in core capercaillie habitat are not a restriction on legitimate recreation but a welfare and conservation necessity. At fewer than 500 individuals, every bird's welfare matters to population viability.
