Bald Eagles average approximately 27 to 43 inches long, average weight is 7 to 14 pounds and can have a wing span of 6 to 8 feet. These magnificent creatures are considered one of the largest birds in the North America. They have a life span of up to 40 years in the wild and even longer in captivity. Eagles can fly up to altitudes of 10,000 feet or more, and can soar for hours using natural wind currents.
Eagles are deeply devoted and mate for life. They share all duties including the hunting, egg incubation, nesting, and the eaglet feeding until the eaglets are strong enough to fly.
The feathers of newly hatched bald eaglets are light grey, and turn dark brown before they leave the nest at approximately 12 weeks.
