Bald Eagle
Conservation
The story of the plight of bald eagles to egg
shell thinning from ingestion of organochlorine pesticides is
one of the most widely and thoroughly documented impacts on
wildlife (review by Buehler 2000). Following a ban on the use
of DDT in North America, numbers have risen exponentially. By
1980 there might have been 70,000 to 80,000 eagles and by 1999
an estimated 100,000 eagles were present mostly in British
Columbia and Alaska. Breeding eagles are now present in many
states and provinces.
