White-tailed eagle (Haliaeetus albicilla)

Classification and relationships

This species is part of the family Accipitridae, which also contains other diurnal birds of prey such as raptors. Within that family the white-tailed eagle is closely related to other large eagles and is a near cousin of the North American bald eagle. It shares many ecological and anatomical traits with hawks and kites (hawks, kites), but differs in habits and size.

Appearance and behaviour

White-tailed eagles are among the largest raptors in their range, with broad wings suited to soaring over coasts, lakes and wetlands. They hunt and scavenge, taking fish, waterbirds and carrion; their powerful feet and hooked bill help handle slippery or struggling prey. They nest in large stick nests placed in tall trees or on cliffs and often reuse and enlarge the same nest for many years.

Range and habitat

The species occurs across much of northern and central Eurasia, favouring coastal waters, river valleys and large inland lakes where food is abundant. Populations are patchy; in some regions they are resident year-round, while in harsher climates individuals may move seasonally to find open water and food.

Conservation and human interactions

Historically the white-tailed eagle declined in parts of its range because of persecution, habitat loss and contaminants. In recent decades protection, habitat management and reintroduction projects have helped many local populations recover. Remaining threats include illegal poisoning, disturbance at nesting sites and collisions with energy infrastructure. The species holds cultural and natural importance in many coastal communities and appears in regional heraldry and conservation programs.

Notable facts

• Adults develop a striking white tail that gives the species its common name.
• They are adaptable feeders: hunting live prey and scavenging dead animals.
• Conservation success in parts of Europe demonstrates the value of legal protection and targeted reintroduction efforts.
