The Bald Eagle is found only in North America. Adult eagles generally weigh between nine and twelve pounds with a wingspan of seven feet. Male eagles are slightly smaller than the females. The distinctive white head and tail of the mature Bald Eagle developes between four and six years of age.

The Bald Eagle feeds mainly on fish, but water fowl and small mammals supplement their diet. The Glendale River Salmon Run starts in mid August and can continue on through the fall. The salmon die shortly after spawning and it is their carcasses which provide a large portion of the Bald Eagles diet.
