In the 1960's, populations of our national symbol, the bald eagle, fell drastically. Pesticides such as DDT accumulated in their prey and thus bald eagles, leading to infertile eggs or eggshells that were too thin. Protection of the bald eagle and its habitat, banning of some pollutants and captive breeding and reintroduction are helping populations recover.
