David Attenborough? the God himself from the wildlife narration? were you referring to Lyre bird sound imitation? didn't watch netflix though (no subscription unfortunately ) because teenage kid at home
but completely unrelated, please watch 'The Last Tepui', a NatGeo movie available on Disney Hotstar. One of the best documentaries i have ever watched. (Alex Hannhold is a legendary climber, you can watch other movies like his free solo climb on El capitan but that is a differemt topic)
