If you saw a Philippine eagle up close, the first thing you would notice is its head. It has a crown of long, brown, spiky feathers, like a wild rock-star haircut. The feathers can stand up when the eagle is alert, making it look even more spectacular.
Philippine eagles live in the tops of giant rainforest trees. They build huge nests of sticks, often 30 metres above the ground - higher than the height of a ten-storey building. A pair will use the same nest year after year, building it up bigger each time.
An eagle pair only raises one chick every two years. The chick hatches from an egg about the size of an avocado. Both parents feed it, taking turns to fly off and bring back food. The young eagle stays with its parents for over a year while it learns to fly and hunt.
The Philippine eagle is very rare - probably fewer than 400 pairs are left in the wild. So scientists and rangers work hard to protect them. There is a special centre on the island of Mindanao where injured eagles are looked after and where children visit to learn how to keep the species safe for the future.
