Most experts expected the bald eagle to become
extinct during the 20th century, but this American
symbol has since reversed its decline and begun
to recover. Experts realized in 1940 that the
species had become endangered, and a law was passed
to offer it protection from hunters- the Bald
and Golden Eagle Protection Act. Even after the
hunting stopped, there was still a decline in
numbers due to the rampant use of DDT. The bald
eagle was included on the endangered species list
in 1973, and the species hit a low point in 1963
with only 417 breeding pairs.
Instead of the expected extinction of the species,
the bald eagle has executed a miraculous rise
in the number of breeding pairs. The more than
9,000 breeding pairs that exist today have made
experts drop the species from the list of endangered
species. Wildlife experts, however, will not be
abandoning the bald eagle. For another five years,
or more, the bald eagle will continue to be tracked
and watched for any decline. The monitoring will
enable the research community to be aware of any
changes in numbers, and for inclusion into the
endangered species list if necessary.
Even without being reclassified as endangered,
the Bald and Golden Eagle Protection Act is still
there to keep the animal from being hunted. The
Migratory Bird Treaty Act of 1918 has offers still
more protection to the bald eagle. The act was
passed to protect migratory birds, such as the
bald eagle, in other countries that share birds
with the U.S. due to migration. For eagles that
make their way into Canada or Mexico, the treaty
is in effect in those countries to stop the trade
of eagle feathers, eggs and other parts that could
make the hunting of eagles lucrative.
The 1972 ban on the use of DDT has also done much
to protect bald eagles. DDT traveled up the food
chain to the bald eagle, and other animals, causing
a steep decline in the number of breeding pairs.
DDT caused a serious decline in bald eagle numbers,
becoming a major contributor to the species’ near
extinction. This chemical eventually made its
way from the waterways and into the eagles. Eagles
then caught the contaminated fish living in these
waters. The affected eagles were unable to produce
eggshells that were hard enough to keep from cracking
before the incubation period was over. DDT devastated
the bald eagle population, as mother eagles were
unable to incubate the thin eggs, often cracking
them in the nest. Today the threat of DDT is largely
over and bald eagles can catch fish, roam the
skies and keep increasing their numbers.
