The female bald eagle is 35 to 37 inches, slightly larger than the male.
With a wingspan which varies from 79 to 90 inches. The male bald eagle has a body length from 30 to 34 inches.  The wingspan ranges from 72 to 85 inches. Bald eagles weigh from ten to fourteen pounds.

The bald eagle is protected by the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act.

The Bald Eagle Protection Act prohibits the take, transport, sale, barter, trade, import and export, and possession of eagles, making it illegal for anyone to collect eagles and eagle parts, nests, or eggs without a permit. Possession of a feather or other body parts of a bald eagle is a felony with a fine of up to $10,000 and/or imprisonment, although federally recognized Native Americans are able to possess these emblems which are traditional in their culture.

Bald eagles are still listed as "threatened" in the United States. (see update above)

Once paired, bald eagles remain together until one dies, the survivor will not hesitate to accept a new mate.

 Bald Eagles feed primarily on fish, but also eat small animals (ducks, coots, muskrats, turtles, rabbits, snakes, etc.) and occasional carrion (dead animals). They swoop down to seize fish in their powerful, long and sharp talons (approximately 1,000 pounds of pressure per square inch in each foot). They can carry their food off in flight, but can only lift about half their weight. Bald Eagles have excellent eyesight. They can see both forward and to the side at the same time. They are capable of seeing fish in the water from several hundred feet above, while soaring, gliding, or in flapping flight.  They seldom dive vertically on their prey, preferring to descend more gradually and snatch fish, rabbits, etc. with their feet. 

Eagles, like all birds, have color vision. An eagle's eye is almost as large as a human's, but its sharpness is at least four times that of a person with perfect vision. The eagle can probably identify a rabbit moving almost a mile away. That means that an eagle flying at an altitude of 1000 feet over open country could spot prey over an area of almost 3 square miles from a fixed position. Their diving speed is estimated at 75 to 100 miles per hour. They can fly to altitudes of 10,000 feet or more, and can soar aloft for hours using natural wind currents and thermal updrafts. 

Young bald eagles have been known to make mistakes, such as attacking objects like plastic bottles floating on or just below the surface of the water. Bald eagles will locate and catch dead fish much more rapidly and efficiently than live fish, because dead fish float with their light underside up, making them easier to see.

Eagles have eyelids that close during sleep. For blinking, they also have an inner eyelid called a nictitating membrane. Every three or four seconds, the nictitating membrane slides across the eye from front to back, wiping dirt and dust from the cornea. Because the membrane is translucent, the eagle can see even while it is over the eye.
