Two Hawaiian Birds on Brink of Extinction to be listed under US Endangered Species Act

September 2008. The U.S. Fish and Wildlife Service has proposed an endangered listing for two rare Hawaiian birds, the Akikiki and Akekee, under the US Endangered Species Act (ESA). The proposal includes listing 48 animals and plants that inhabit the Island of Kauai, and will utilize a new ecosystem-based approach to their conservation and the designation of Critical Habitat.

  1. Wildlife officials hope to save Hawaiian crow from extinction with $14M plan

    HONOLULU – Federal wildlife officials say they plan to spend more than $14 million to prevent the extinction of the Hawaiian crow, one of the rarest forest birds in the world.

    The endangered bird, known as the alala, is only found in captivity on the Big Island.

    Two bird conservation centers are home to 56 alala. The bird hasn’t been seen in the wild since 2002.

    The U.S. Fish and Wildlife Service says its five-year plan to restore alala populations includes protection of habitats and management of threats to the species.

  3. Catastrophic mass extinction of birds in Pacific Islands followed arrival of first people, research shows March 25, 2013

    Research carried out by the Zoological Society of London (ZSL) and collaborators reveals that the last region on earth to be colonised by humans was home to more than 1,000 species of birds that went extinct soon after people reached their island homes.

    The paper was published today (25th) in the journal Proceedings of the National Academy of Sciences. Almost 4,000 years ago, tropical Pacific Islands were an untouched paradise, but the arrival of the first people in places like Hawaii and Fiji caused irreversible damage to these natural havens, due to overhunting and deforestation. As a result, birds disappeared. But understanding the scale and extent of these extinctions has been hampered by uncertainties in the fossil record. Professor Tim Blackburn, Director of ZSL’s Institute of Zoology says: “We studied fossils from 41 tropical Pacific islands and using new techniques we were able to gauge how many extra species of bird disappeared without leaving any trace.” They found that 160 species of non-passerine land birds (non-perching birds which generally have feet designed for specific functions, for example webbed for swimming) went extinct without a trace after the first humans arrived on these islands alone. “If we take into account all the other islands in the tropical Pacific, as well as seabirds and songbirds, the total extinction toll is likely to have been around 1,300 bird species,” Professor Blackburn added. Species lost include several species of moa-nalos, large flightless waterfowl from Hawai’i, and the New Caledonian Sylviornis, a relative of the game birds (pheasants, grouse, etc) but which weighed in at around 30kg, three times as heavy as a swan. Certain islands and bird species were particularly vulnerable to hunting and habitat destruction. Small, dry islands lost more species because they were more easily deforested and had fewer places for birds to hide from hunters. Flightless birds were over 30 times more likely to become extinct that those that could fly. Bird extinctions in the tropical Pacific did not stop with these losses. Forty more species disappeared after Europeans arrived, and many more species are still threatened with extinction today.
