Its dive speed is , though it does not dive a lot. The bald eagle is usually migratory, which means that it travels (migrates) between homes which are very far away from each other. In some places, bald eagles are not migratory. If a bald eagle's territory has water near by, it will remain there all year. But if the water where it lives freezes in the winter, it must migrate to the south or to the coast to find something to eat.
