Rare parrots lay a record
![]() Not quite as rare as it used to be: The kakapo is breeding back from the brink
Today that number has risen by a third, to 84 birds, thanks to a bumper brood of chicks. The parents have had some help from their human protectors, but have done most of the work themselves. Experts say the kakapo's survival prospects are now distinctly brighter than they were a short time ago. The kakapo is the world's rarest parrot, its heaviest, and the only nocturnal and flightless parrot. It is a native of New Zealand, where all the survivors live. Great news The country's Department of Conservation (DoC) announced on 18 February that 18 females were incubating 52 eggs on Whenua Hou, a small island off the coast of New Zealand's South Island, and the first chick hatched two days later. The DoC now says 22 chicks have hatched on Whenua Hou, a record. The director of BirdLife International, a worldwide alliance of bird conservation groups, said the announcement was "the best news for threatened bird conservation in recent years". Daryl Eason, one of the team on the island, said infertility was still a big problem. He said: "We've had 61 eggs laid, and 22 chicks. When you see that wasted potential, it's really sad. But on the other hand, to have 22 chicks is just fantastic." High-tech help The DoC says eggs were still being laid on 16 March. It says the previous high mortality rate has been reduced because experts know more about protecting the kakapo.
Rats were eradicated on Whenua Hou in 1999, making the island one of the safest environments for the birds. The kakapo are also thriving this year because the rimu trees on the island are bearing abundant fruit. The rimu is an important food source for young kakapo, but it has had only three good seasons in the last decade. Sleepless nights To improve their prospects, each kakapo is fitted with a radio transmitter, and their nests are monitored by infrared cameras throughout the breeding season. While the females forage, warming pads are placed over the eggs and nestlings. And any chicks that are neglected or become ill will be removed from the nests and hand-reared by DoC staff. More than 20 volunteers spend two weeks each on the island, guarding the birds. There is a waiting list of volunteers, undeterred by the prospect of little sleep as they watch over the nocturnal kakapo. Images courtesy of Don Merton/DoC
