Baby boom for world's rarest parrot
In a land renowned for unusual creatures, New Zealand’s "owl parrot" or kakapo is surely a candidate for the most outrageous. The size of a small dog but with stature of a penguin, this large, rotund bird has an owl shaped head and cat-like whiskers.

One aspect the kakapo has in common with some of its airborne cousins is extreme longevity, with certain individuals known to live for 120 years.

When this painfully slow reproductive rate is coupled with an inability to escape the jaws and claws of a whole host of introduced predators, it is perhaps no surprise that just 25 years ago, the kakapo (Strigops habroptilus) was being earmarked for extinction.

Since then a small and dedicated team using artificial insemination, artificial incubation, and careful nest management of wild birds has slowly but surely increased their population to 123 adults, all contained within three small, predator-free islands.

To put this figure into context, only six chicks were raised during 2014, making the "Class of 2016" all the more significant. Deidre Vercoe, operations manager of Kakapo Recovery explains that she has been waiting 18 years for a breeding season like this. "In 1990, only one bird survived from mainland New Zealand to join the recovery programme, whilst the other 50 kakapo originated from Stewart Island. This mainland bird, named Richard Henry, was genetically distinct, and bore three offspring in 1998." After a long and anxious wait, this year Richard’s only daughter produced four chicks of her own.

The coming weeks will be crucial, since the young kakapo are still not out of the woods. Back in March, for example, a flash flood killed three individuals. As each egg hatches, Deirdre’s team regularly check and weigh the chicks until the point they fledge at around 10 weeks. Each chick is so crucial to the survival of its species, that if it is found to be struggling in the wild, it will be swiftly brought in for hand rearing. And although they are now four months old, their delicate nature means the chicks won’t be added to the total kakapo head count until October. DNA analysis is also being undertaking to confirm sex and parentage of all the chicks, which will allow the team to constantly assess the genetic diversity of the population, in addition to gauging whether artificial insemination was successful.

Sirocco, a hand-raised kakapo, even possesses his own Facebook page. "Now is the time to keep up the momentum with recovery efforts to ensure the Kakapo continues to strengthen," adds Maggie Barry, New Zealand’s Minister for Conservation.
