About the White-tailed Eagle

The White-tailed Eagle (Haliaeetus albicilla) is also known as the ‘sea eagle’. It is the largest eagle in Europe, with a wingspan ranging from 2 to 2.4 metres (6.5 to 8 feet). Female White-tailed Eagles weigh up to 7 kg (15 pounds). Males weigh less, up to 5.4 kg (11.9 pounds).

White-tailed Eagles have brown plumage that is slightly brighter on their head and necks. As their name suggests, their tails have distinctive white feathers. However, younger species look different. They are entirely brown; their tails turn white over time. It usually takes about five years for an eagle to develop this characteristic.

They nest on sturdy trees or cliffs near large bodies of water, such as sea coasts, wetlands, lakes and rivers. Fish is their main food source, but they are opportunistic feeders and can feed on other birds, hunt small mammals and scavenge on dead animals. White-tailed eagles are excellent hunters. Their vision is incredibly sharp and they have large curved beaks that help them tear into their prey. Living near water provides them with a great opportunity to soar above large open spaces and spot their prey.

White-tailed Eagles used to be endangered mainly because of hunting and habitat loss. Luckily, due to conservation efforts, their population increased and today, they are classified as Least Concern by IUCN.

Most countries where White-tailed Eagles are found have legislation in place to protect the populations of these birds. These laws protect their habitat, forbid hunting and support conservation programs. The main threats to White-tailed Eagles come from human activity. Deforestation and degradation of wetlands reduce their nesting and hunting grounds. Other threats to these birds include pollution and collisions with wind generators.

Climate change can affect fish populations, which are the primary source of food for White-tailed Eagles. Changes in food availability can affect the birds’ survival rates.
