Paradise
Lost |
Paradise to a "snowbird" is vacationing
on a tropical island, with lush green vegetation, azure blue
seas, and exotic birds filling the air with song from the first
break of day to the surrendering light of dusk. We west coast
vacationers may say that such paradise is found on one or all
of the Hawaiian islands. Flying over the vast Pacific Ocean,
one arrives at a Hawaiian airport and is greeted by beautiful
natives who reach over your head, gifting you with a colorful
lei of fragrant, native flowers. "Aloha." Ahh,
yes, you have arrived on the paradise island. But paradise isn't
always as exotically charming as it first appears. Well, maybe
to the brief visitor, but not to the native birds. Specifically
the Palila (Loxioides bailleui), an endangered Hawaiian honeycreeper.
Because of its dramatic decline in numbers in such a short
period of time, it has had the longest history of monitoring
of any of Hawai'i's forest birds. |

The Palila is increasingly
becoming restricted to the west slope of Mauna Kea, occupying
less than 5% of its historical range. Palila depend on mamane
(Sophora chrysophylla) forest for the majority of their dietary
intake as well as for nesting sites and shelter. The quantity
and quality of this dry subalpine mamane woodland has declined
over many decades due the grazing pressure of introduced herbivores
but is beginning to recover in many areas where ungulate numbers
have been reduced. |
However, despite
improving habitat conditions, the palila has not increased
in numbers. Restoration techniques are needed in order to speed
the recovery of the palila population and return it to areas
of its historic range, thus preventing extinction due to catastrophic
events. These techniques are being developed through population
monitoring, habitat management research, translocation, and
breeding enhancement.
