1. The kakapo is a species of large, flightless, nocturnal, ground dwelling parrot.
2. Endemic to New Zealand, it's actually the world's only nocturnal, flightless parrot.
3. It looks like an owl, or a giant budgie.
4. It's been called one of the ugliest birds on Earth.
Which seems a little harsh.
5. A relic of a bygone age when it had no predators, it is the rarest parrot on Earth.
7. And his mate Mark Carwardine, a zoologist who found himself the object of a lusty kakapo's affections in an infamous BBC nature documentary.
Frisky. Very frisky.
8. Amorous chap Sirocco was given the title of Official Spokesbird for Conservation by New Zealand Prime Minister John Key in 2010.
10. It's estimated there are fewer than 130 kakapos left in the wild.
11. This is actually a big increase on 1989, when the population numbered just 65 birds.
12. Today there are kakapo breeding populations on three predator-free islands.
13. Unable to fly, the kakapo has plenty of time to bulk up, making it the world’s heaviest parrot.
Kakapos can weigh up to 4kg.
14. It walks and jumps and is an excellent climber.
15. It feeds on the ground or 20m up a tree.
17. It “skraarks” loudly like other parrots but you might mistake other calls for a braying donkey, a squealing pig, or a booming bittern: LISTEN.
19. It’s possibly the longest-lived bird species in the world.
The low adult mortality rate suggests a mean life expectancy of 90 years.
20. Kakapo have inhabited New Zealand for thousands of years but, with the arrival of humans and introduced predators, their once abundant numbers rapidly declined.
21. A small team of dedicated staff from New Zealand's Department of Conservation have worked tirelessly to protect, manage and grow the kakapo population.
22. They have been supported by volunteers who provide extra support – by nest-minding and supplementary feeding – during the precious breeding seasons.
23. Last week a new kakapo hatched from a broken egg!
