I'm not sure TBH - the bird flies over some trees but circles back a bit before landing and it's quite possible they saw the rough area it landed in, and it would be fairly easy to spot a Kea laying into a GoPro from a reasonable distance.

and some also have GPS, all of which can aid in locating them if you're within range.
