Nests

Eagles nests consist of layers of old prey femains.  Large sticks, some over six feet long and two inches think are woven together to form a nest.  Sticks are found on the ground or dead branches are disloged from the trees by flying against a branch feet first.  The course frame of large sticks interwoven with smaller sticks and the center is filled with dred weeds, stubble,and sod.

 
They are built in strong, tall trees around lakes, rivers, and sea coasts so they can have a clear view of their surroundings.  Eagles nests can be up to twenty feet thick and almost ten feet deep.  A hollow that is formed in the center is twenty inches across and four or five inches deep.  Bald eagles build the largest nests of any bird in North America.  An old nest in good repair can weigh up to two tons, so sometimes the trees collapse from the weight of the nests.The shape of the nests is determined by the configuration in wich the tree is built.  A pair of eagles can occupy a nest for decades.
