Bald eagles are extremely slow to re-colonize former territories or pioneer in new areas, so in areas the number of eagles are no longer found, reintroducing them may help population recover.  Several southeastern states have cooperated on a reintroducing program in which eggs are removed from the wild nests in Florida, artificially incubated and reared, and then " hatched" into appropriate areas where they are to be reastablished.

 At six to seven weeks of age, young birds are placed in large cages on platform, called hacking towers, where they are fed and protected.  When the eagles are about eleven to twelve weeks old the cages are opened and the birds are free to fly away.
