Twenty Years Later Many Bird Species Still
Have Not Recovered
from Exxon Valdez Oil Spill

(March 23, 2009) Many species
of wildlife were decimated when the Exxon Valdez spilled nearly
11 million gallons of crude oil into Prince William Sound,
Alaska on March 24, 1989. While many are showing signs of
returning to normal populations levels, several bird species
have not yet recovered, and the status of five others remains
unknown.
“Twenty years after
the Exxon Valdez spill, oil still poses a grave threat to
marine birds. American Bird Conservancy would like to see
an acceleration of the phase out of single hulled tankers
in the U.S. which are allowed until 2015,” said Dr.
Michael Fry, American Bird Conservancy’s Director of
Conservation Advocacy. “A similar requirement for double-hulled
tankers needs to be made globally to protect birds and other
wildlife from future spills. Additional marine reserves and
no-go zones for tankers during sensitive breeding and staging
seasons should also be implemented to protect the most vulnerable
species.”
The Exxon Valdez Trustee Council
has found that Exxon Valdez oil persists in the environment
to this day in places, and is nearly as toxic as it was when
the spill occurred. At the rate this oil is dissipating it
will take decades, perhaps even centuries to disappear entirely.
“Analysis of the oil
spills’ impacts found that a significant portion of
several species’ populations were killed, including
5-10% of the world’s Kittlitz’s Murrelet population
and 6-12% of the area’s population of the Marbled Murrelet,”
said Dr. Fry. “We are concerned about a number of the
bird species harmed in the catastrophe such as the Kittlitz’s
Murrelet whose population has yet to rebound.”
Kittlitz’s Murrelet, a candidate for listing under the
Endangered Species Act, declined 99% from 1972 to 2004. Prior
to the spill, the rate of decline was 18% per year, but since
1989 that rate has increased to 31%. The growing impact of
global warming in the Arctic and the melting of glaciers,
caused by the burning of oil and other fossil fuels, may also
be a factor in this decline.
Monitoring of bird species
has found that the Pigeon Guillemot is not recovering in the
spill area and that populations have been steadily declining
throughout the Sound since the spill. Similarly, the Marbled
Murrelet has not met the recovery objective of an increasing
or stable population.
Oil is very toxic to birds,
and water birds such as murrelets are particularly susceptible
to harm because they come into direct contact with the oil
floating on the surface of the water. Once feathers become
oiled, they lose their insulating properties and the birds
freeze to death, or are poisoned when they try to clean it
off. Research has found that Harlequin Ducks and Black Oystercatchers
also suffered from chronic injury related to long-term exposure
to lingering oil that remains in the area.
