The amazing bald eagle—Haliaeetus leucocephalus—is Canada's largest bird of prey and the only eagle exclusive to North America. An apex predator with no natural enemies, the bald eagle has long been a potent symbol of vision, power, and stoicism. The adult boasts a wing span of more than 2 metres, a standing height of about 1 metre, and an average weight of up to 7 kilograms. Females are generally larger than males. The renowned raptor is noted for its distinctive dark-feathered body and white-feathered head, large golden eyes, bright yellow beak, and massive yellow claws armed with sharp, powerful talons. This long-lived bird can survive nearly 30 years in the wild and even longer in captivity. Nesting in tall trees near large bodies of water and well away from human habitation, bald eagles survive on a diet of fish, birds, invertebrates, and small mammals, but are opportunistic feeders who will also steal from other predators and eat carrion.
