The population of New Zealand's kakapo, an endangered flightless parrot, has increased 25% in the last year to 252 birds following a good breeding season and success with artificial insemination, the conservation department said Tuesday.
The kakapo have been nearly wiped out by introduced predators such as stoats as the birds cannot fly. The problem has been exacerbated by inbreeding, very low fertility - only 50% of eggs are fertilised - and as they only breed every two or three years when native rimu trees fruit.
