(Washington, D.C.) American Bird Conservancy
and Dr. Eric VanderWerf, an acknowledged expert on Hawaiian
birds, submitted a petition yesterday to the U.S. Fish and
Wildlife Service requesting protection under the Endangered
Species Act for the Akekee and the Akikiki, two very rare
birds found only on the Hawaiian Island of Kauai. Recent population
surveys are raising concern that these species may be on the
brink of extinction.
“Recent surveys show that the Akikiki
and the Akekee are seriously in trouble,” said George
Fenwick, President of American Bird Conservancy. “The
strongest available measures such as captive-breeding, fencing
out and removal of invasive species, and listing under the
Endangered Species Act, are all necessary to prevent these
species from going extinct.”
The current population of the Akikiki could
be as few as 782 birds, based on surveys conducted in April
and May 2007. The population has steadily declined from around
7,000 birds in 1970 to this year’s all time low. The
geographic range occupied by the Akikiki declined from 34
square miles in 1970 to 14 square miles in 2000, and may have
continued to decline since then.
The current population of the Akekee is
estimated to be as low as 2,506 birds, based on surveys conducted
in April and May 2007. The population has declined from around
8,000 birds in 2000. The geographic range occupied by the
Akekee was also approximately 34 square kilometers in 1970,
and although this was reported not to have changed in 2000,
surveys in 2007 failed to find the species in many areas where
it was previously observed. This would indicate that there
has been a range contraction, though the extent is not known
at this time.
The primary threats to the Akikiki and
Akekee are habitat loss and degradation caused by invasive
alien plants and browsing and rooting by feral pigs, diseases
spread by introduced mosquitoes, predation by alien mammals
such as rats, and catastrophes such as hurricanes. Some of
these threats are severe in magnitude, and are occurring over
a significant portion of the species’ ranges. The threat
from mosquito-borne diseases may worsen as global warming
allows mosquitoes to invade the highest, coldest parts of
the island that once provided refuge from disease.
The Akikiki and Akekee are not adequately
protected by existing regulatory mechanisms. The Akikiki is
categorized as critically endangered by the World Conservation
Union (IUCN) due to its extremely small and declining population
and geographic range. The Akekee is categorized as endangered
by the IUCN due to its small and declining geographic range
and declines in habitat quality.
Hawaii leads the U.S. in the
total number of endangered and threatened species with 329,
and in extinctions – with over 1,000 plants and animals
having disappeared since human colonization. When Captain
Cook landed on the islands in 1778, there were at least 71
endemic bird species. Since then, 26 of those species have
gone extinct, and 32 more are now listed under the Endangered
Species Act as threatened or endangered. Several Hawaiian
bird species, the Poouli and the Ou are assumed to have recently
gone extinct before captive-breeding or other protection measures
could be implemented.
