The Kakapo Recovery Program, a conservation group that helps monitor and manage the few kakapos left in the wild, was dealt a disappointing blow following the discovery of a sixth dead bird in the past year.
The kakapo, named Barnard, was found dead by rangers on Whenua Hou/Codfish Island in New Zealand when they went looking for him to perform his annual transmitter change.
Kakapo Recovery Program manager Deidre Vercoe Scott said the team was gutted by Barnard? death, especially since it appeared to have gone unnoticed for up to three months.
?hile it? true we only sight these birds once a year for health checks and a transmitter change, Kakapo Recovery prides itself on having technology that allows us to monitor our precious population, with minimal interference,?Scott said. ?ut that technology is constantly changing to increase the information that we can collect. We may be experiencing some problems with how we interpret these complex transmitter signals accurately, so we will be looking into this closely. While it won? prevent a kakapo death, identifying a mortality signal as soon as possible means we get better information from the autopsy examination.?lt;/p>
Barnard was an unknown-aged bird, first discovered on Stewart Island in 1982. He fathered eight chicks, including five of the 11 hatched during the last breeding season in 2011. His death reduces the kakapo population to125 parrots.
Scott said kakapo deaths were a reminder that, although the Kakapo Recovery Program had achieved much during the past 22 years ?increasing the total population from 49 to 131 last year ?the kakapo is still a critically endangered parrot species and vulnerable to extinction. And, with an ageing population, an increase in mortality was inevitable.
?e can expect to see the population numbers continue to go up and down for several years to come because quite a few of the birds are possibly very old,?Scott said. ?he good news is more than half the kakapo population consists of young, breeding-age birds and indications are that there will be a breeding season this summer ?planning for that is well underway.?lt;/p>
