Signs of Recovery for Scotland's Endangered Capercaillie

The capercaillie, a grouse species native to the Caledonian pine forests of the Scottish Highlands, has faced significant population declines over the past few decades. Once numbering over 20,000 in the 1970s, the population fell to a mere 532 individuals by 2025, marking the lowest levels recorded since monitoring began more than 30 years ago. Contributing factors to this decline include adverse weather conditions, habitat loss, increased predation, and human disturbances, including potential disruptions from social media attention.

Despite these challenges, recent conservation efforts have yielded promising results. At RSPB Abernethy, the population of lekking male capercaillies increased by 50%, from 20 males in 2020 to 30 in 2025. This site now hosts over 20% of the 143 lekking males counted in the national survey of 2025. Conservationists attribute this positive trend to innovative habitat management techniques, including the use of a remote-controlled mower to manage heather and promote the growth of blaeberry, a vital food source for the birds.

Richard Mason, conservation manager at RSPB Abernethy, emphasized the importance of habitat quality improvement in supporting the capercaillie's recovery. The combination of cutting and targeted cattle grazing has significantly enhanced forest conditions, allowing more chicks to reach maturity. Additionally, virtual fence collars on cattle have facilitated grazing in areas that are difficult to fence, minimizing collision risks for the flying capercaillie.

The recovery of the capercaillie is not only vital for the species itself but also serves as a case study for conservation efforts across Scotland. The recent positive counts in other forests, such as Strathspey, indicate that similar strategies may be effective in other regions. Mason noted, “There is still a lot of work to be done for capercaillie, not just at RSPB Abernethy, but across all capercaillie sites in Scotland.”

While the recent increases are encouraging, experts caution that the future of the capercaillie remains uncertain. The species continues to face threats from habitat degradation and low genetic diversity. Conservationists stress the need for ongoing efforts to enhance native pinewood forests to ensure the long-term survival of this iconic bird.

The capercaillie's gradual recovery in Scotland highlights the potential for targeted conservation strategies to reverse declines in endangered species. As efforts continue, the hope is that these techniques can be replicated across other habitats to support the recovery of not only the capercaillie but also other vulnerable wildlife in the region.
