Golden eagles get their name from the warm golden-brown feathers on the back of their head and neck, which glow in the sun. The rest of their body is dark brown. Young eagles have white patches on their wings and tail that disappear as they grow up.
An eagle's eyes are its main superpower. They can spot a rabbit moving from a kilometre away. Each eye has two 'focus points', which means they can look at something far away and something close-up at the same time. If we had eyes like that, we could read a book and watch a film at once.
Golden eagles hunt by riding high on warm air, then folding their wings and diving. At the bottom of a dive they can be travelling at over 240 km/h - faster than a Formula 1 car. They snatch their prey with huge curved talons (claws), and can carry off animals as large as a mountain hare.
Eagle pairs stay together for their whole lives, and they often return to the same enormous nest year after year. Each year they add a few new sticks. After many years, a golden eagle nest can become 2 metres wide and 3 metres deep - heavy enough that it sometimes pulls a whole branch off the cliff.
