I really enjoyed the video captured from the ground! I suppose the trajectory was super well characterized so the camera could stay on target. Also, the evening launch and position of the sun in the sky helped too I'd guess.
Lyrebirds can perfectly mimic almost all sounds so aussies, who know this, like to use our mobiles to play recordings of movie sound effects to lyrebirds to see if we can get them to copy. This bird is obviously used to humans, I'm guessing that's what happened.
