AP BIOLOGY

Detailed explanation-1: -Extremely large wingspans–sometime more than 7 1/2 feet–allow them to easily catch the currents and drift through the air. This conserves a lot of energy, meaning they can stay up in the air looking for prey for a longer amount of time before tiring.

Detailed explanation-2: -The Founding Fathers made an appropriate choice when they selected the bald eagle as the emblem of the nation. The fierce beauty and proud independence of this great bird aptly symbolizes the strength and freedom of America.

Detailed explanation-3: -An eagle’s wings are not the only adaptation that allows them to fly so gracefully. Their tail is another critical piece, as it’s the perfect length and width to keep the eagle’s head from being dragged down during flight. The hearts and lungs of an eagle help out as well.

Detailed explanation-4: -They can swoop down on prey at incredible speeds. And once they have caught it, they can lift very heavy prey into the air. (Some eagles can even fly away with prey that weighs more than they do). When an eagle first leaves the ground, it gains altitude by flapping its wings.

Detailed explanation-5: -The eagle’s impressive wingspan allows it to fly at speeds of up to 20 miles per hour. It floats across the air thermals; the vertically spiraling columns of warm air allow the bird to fly effortlessly. The bird uses virtually no energy when flying. Its hollow skeleton also helps the bird fly.
