This 25 June 2019 video is about three young griffon vultures. They grew up, cared for by same sex parents and injured wings parents, in the big vulture aviary in Artis zoo in Amsterdam, the Netherlands.
They were brought to Sardinia island in Italy. After a stay in a local aviary to get used to the change, they were freed on 25 June 2019.
Probably, they will join a local flock, like the Artis-born vultures freed there last year did. They have GPS trackers on, so researchers can study where they go, like the other griffon vultures freed last year.
