Endemic New ZeaLand FlightLess Parrot: Kakapo

It is the only nocturnal parrot and also the heaviest in the world, weighing up to 3.5 kilograms (8 lbs). The kakapo is a unique parrot species because it can´t fly!
It’s probably the longest-lived bird species in the world; the low adult mortality rate suggests a life expectancy of 90 years 

The arrival of Polynesian thousands of years ago, Europeans in the 1800's and the pets and livestock they introduced resulted in the massive decline of Kakapo populations from hundreds of thousands to just 62! 
After 20-30 booms they then make a high-pitched metallic call, or ‘ching’.
