At ENDESU we have worked for several years in the care of the golden eagle and its habitat, identifying and attending areas of opportunity for its protection. However, year after year the recognized areas in Mexico with the highest reproductive activity have been reduced as a result of the change in land use that occurs in their hunting and nesting territories. This change leads to the loss of prey and without food, the eagles do not nest nor procreate, or the chicks run the risk of dying. Without young fledglings, eagle populations age and decrease in number.
