This species is one of the most endangered in the world. According to Wikipedia, there are perhaps 900 of them living free and about 1000 in zoos !

A photo not to be proud of, but let me explain you: I visited a palm house in Vienna, never been there before. It was a rather unattractive place, and the humidity caused sweating.
To my biggest surprise suddenly 4 of these amazing birds flew around me. You can easily imagine that the atmosphere changed to awesome in a second !! 
Flash was not allowed, and it was really dark !! So first: excuse me posting a captive bird, second the poor quality ! I will repeat this visit.
