Golden Eagle vs Bonelli's Eagle

The Golden Eagle is a large, strong bird of prey with dark brown feathers and distinctive golden-coloured feathers on the head and back of the neck. Adults are between 75 and 90 centimetres long, with wingspans reaching up to 2.2 metres. When flying, they hold their long wings in a shallow V shape, with spread-out primary feathers at the tips and a broad, slightly rounded tail. Young birds have white patches near the base of their wings and a white tail with a dark band at the end. In the UK, Golden Eagles are mostly found in the Scottish Highlands and nearby islands. There are small numbers in southern Scotland, and there have been efforts to reintroduce them in southern England. They prefer open upland areas like moorland, mountainous regions, and remote valleys. They need large open spaces to hunt and cliffs or old trees to build their nests. Golden Eagles hunt animals such as mountain hares and rabbits, as well as birds like grouse. They also feed on dead animals when available.

Bonelli's Eagle is a medium-sized bird of prey with clear markings that help to recognise it. Adult birds have dark feathers on their upper parts and lighter feathers underneath, which are marked with dark streaks. When flying, a distinctive white patch on the back can be seen. The tail has a wide dark band at the end. Young birds are reddish-brown on top with paler, less streaked feathers underneath. The eagle lives in rocky, mountainous areas and wooded hills around the Mediterranean region, parts of southern Asia, and some areas in North Africa. In Europe, it usually stays in the same area where it breeds. This bird is a strong hunter, catching medium-sized birds and mammals with skill as it moves through rough terrain. It often hunts in pairs. The number of Bonelli's Eagles has fallen in some areas, leading to concern for its future in several European countries.
