Capercaillie Welfare and Conservation

Capercaillie are iconic forest grouse that have declined to critically low numbers in Scotland and require intensive welfare-conscious conservation.

Key Facts

Scottish capercaillie populations have declined to fewer than 1,000 birds, making them critically endangered
They require old Caledonian pinewoods with bilberry, heather, and specialist invertebrate communities
Fence collisions cause significant mortality and injury among capercaillie in managed deer forests
Disturbance at lek sites during the spring display period can cause breeding failure across entire populations

Welfare Considerations

Capercaillie welfare is affected by multiple compounding threats that make their conservation critically urgent. Fence collisions cause traumatic injuries including broken wings and legs, leading to death from inability to feed or escape predation. Each fence strike represents direct acute welfare harm to an individual member of an already critically small population. Disturbance at lek sites — by walkers, mountain bikers, and photographers — disrupts the complex spring breeding behavior that capercaillie males engage in for weeks, reducing breeding success and causing chronic stress. The welfare of each individual capercaillie is of conservation significance given population size.

What You Can Do

Avoid entering known capercaillie lek sites from October through May without specific permissions
Support RSPB Scotland and other organizations working on capercaillie recovery programs
Advocate for fence marking and removal in capercaillie habitat to reduce collision mortality
Engage with visitor management at forest sites where capercaillie are present to reduce disturbance
