Wales: A Home for White-tailed Eagles

White-tailed Eagles were once a natural part of the Welsh landscape, closely associated with coasts, estuaries and freshwater systems. Although now absent as a breeding species, these environments remain widely distributed across Wales. 

Using species distribution modelling, our research identifies where modern Welsh landscapes continue to provide suitable breeding habitat for White-tailed Eagles. The results highlight extensive areas of coastal and inland environments capable of supporting roosting, nesting, and foraging.  This evidence demonstrates that Wales remains firmly within the species’ natural ecological range and continues to provide the conditions required for breeding White-tailed Eagles today.

 
 

White-tailed Eagle Habitat Requirements

White-tailed Eagles occupy a distinct ecological niche compared to Golden Eagles, favouring lowland landscapes associated with water. Key requirements include low elevation (<124 m asl), proximity to coast (<700 m), and proximity to inland water (<431 m from lakes and rivers). Breeding territories are typically centred around coastlines and estuaries, rivers, lakes and wetlands, with forested areas or cliffs providing suitable nesting sites. Together, these features provide reliable food sources and nesting structures, supporting breeding pairs across both coastal and inland environments.

 

Lowland Elevation & Coastal Proximity

White-tailed Eagles favour lowland environments (<124 m asl), particularly along coastlines (within ~700 m), where marine habitats provide consistent food resources and suitable breeding territories.

Freshwater & Wetland Systems

Access to freshwater and estuarine systems is essential, with eagles typically found within ~431 m of lakes and rivers, including estuaries, wetlands and watercourses, which provide feeding opportunities and support a wide range of aquatic prey.

Nesting Structure, Space & Foraging Landscape

White-tailed Eagles require suitable nesting structures in forested areas or coastal cliffs, alongside open landscapes for foraging and large, connected territories that allow movement, hunting and successful breeding.

 

How much of Wales is Suitable?

At a national scale, Wales contains a substantial proportion of suitable habitat for White-tailed Eagles. Habitat modelling identified 38.3% of Wales as suitable breeding habitat, distributed across 14 coastal and 3 inland bio-geographic zones. Key areas include Anglesey and the Llŷn Peninsula, the Ceredigion and Pembrokeshire coastlines, and major estuaries and freshwater systems.

When compared with historic and modern eagle records, 77% of records fall within these predicted areas, providing strong validation of the model.

Why is Wales Important?

Across southern Britain, Wales represents one of the most important areas for White-tailed Eagle habitat. It retains extensive, connected coastlines, large estuaries and wetland systems, and a mosaic of marine and freshwater environments.

These features closely match the species’ ecological requirements, positioning Wales as a key region for potential restoration. Importantly, Wales is not just historically relevant — it continues to provide large, relatively unfragmented areas of suitable habitat, particularly along its western and southern coasts.

A landscape still capable of supporting Eagles

White-tailed Eagles are no longer part of the Welsh landscape, but the environments they depend on remain. By combining historic evidence, habitat modelling, and ecological understanding, we can see that Wales continues to offer extensive coastal and freshwater environments capable of supporting breeding birds.

This provides a strong scientific foundation for assessing how a lost native species might one day return — grounded in ecological reality and supported by evidence.
