Cairngorms Falcon Population Halved: Research Reveals Steep Decline
27 Nov, 2025
Summary
- Peregrine falcon numbers in Cairngorms National Park have decreased by 56%.
- This decline has occurred over the past two decades, since 2002.
- Factors include prey scarcity, land management, crime, and avian flu.

The majestic peregrine falcon population within Cairngorms National Park has experienced a dramatic reduction, potentially halving over the last two decades. A comprehensive survey conducted last year by the Scottish Raptor Monitoring Scheme revealed a stark 56% decrease in breeding pairs compared to figures from 2002. This alarming trend is compounded by a widespread failure among the remaining pairs to successfully raise their young.
Several interconnected factors are being investigated as potential causes for this significant downturn. Researchers suggest that a decrease in the availability of prey species, coupled with specific upland land management practices, may be impacting the falcons' ability to thrive. Additionally, ongoing concerns regarding wildlife crime and the devastating effects of avian flu are considered significant contributors to the population's decline.
These findings underscore a critical conservation challenge for one of Scotland's most iconic wild landscapes. The study's results point to a complex interplay of environmental and human-induced pressures affecting the park's apex predators. Urgent attention and potential interventions will be necessary to address the factors contributing to the falcons' diminishing numbers and ensure their future in the Cairngorms.
