"This is a song recording of a male o'o singing on Kauai. These birds mate for life, so he would be singing a duet with his mate where he sings and she sings back. Here comes the male song... there's no response. The male song again... that's the last male of a species singing for a female who will never come. He is totally alone. And now his voice is gone
It's like having a symphony and one-by-one, you just pluck each of thе instruments out of the orchestra, until your last voicе is there, and then... it's gone."
