Eagle Reintroduction Wales are exploring the viability of returning these two stunning species to Wales.

The extinction of golden eagles and white-tailed eagles in Wales was human-mediated through persecution, with both species wiped out of the Welsh landscape by the 1850s.

When considering the reintroduction of wildlife into a region, there needs to be a clear understanding of how changes during the species’ absence may impact their presence today. Eagle Reintroduction Wales sets out to provide evidence for whether the modern-day Welsh environment is still suitable for golden eagles and white-tailed eagles.

Eagle Reintroduction Wales are conducting a feasibility study to explore the factors that may impact the success of reintroducing golden eagles and white-tailed eagles in Wales. This includes understanding the role of environmental factors such as climate change now and in years to come, as changing environmental conditions can impact the suitability of landscapes for breeding eagles.

With eagles being absent from the landscape, the study of model species that are present in Wales now is also a key component of this research, as ecologically-similar species can provide insights into the potential success of eagles once again living in Wales. Peregrine falcons are being studied as a model species to assess if the climate conditions of upland Wales are feasible to restore golden eagles.

NatureSpy supported the projects’ trail camera studies through a combination of equipment loans and technical assistance. Trail cameras were used to observe and assess peregrine falcon chick provisioning rates, diet and survival. Combined with environmental data, this enables the ERW team to assess if the provisioning and survival of peregrine chicks is being affected by climate change. 

The use of trail camera photos and videos helps the team to observe nesting activity and behaviours throughout the breeding season. Clear images are key to gaining insights and cameras that can last a long time on a set of batteries are essential to avoid disturbance to the birds while nesting. The project used Browning Recon Force trail cameras as they combine clear footage with long, efficient battery life.
