What are the adaptations of a bald eagle?

The bald eagle is both the national bird and the national animal of the United States. It has a number of adaptations, some of which are listed below:
A bald eagle has much better eyesight than many other species. They can see a small fish from high up in the sky. This is made possible by a super-sensitive retina. A bald eagle's retina is five times more light-sensitive than that of a human, providing it much better eyesight.
Another vision-related adaptation is the presence of a bony ridge above their eyes that helps in minimizing the glare from the Sun.
They have very sharp talons that allow them to capture and kill prey. The sharp talons are capable of penetrating the prey's flesh.
They have large curved beaks that allow them to tear the prey's flesh and eat it. The beaks are made of keratin, the same material that forms our toenails and fingernails.
They have an extremely large wingspan (as long as 8 feet), which allows them to drift easily in the air without spending too much energy. The wings also provide a lifting power of about 4 pounds.
