This 10 January 2018 video from Artis zoo in Amsterdam in the Netherlands says about itself (translated):
Today two young griffon vultures (Gyps fulvus) are going from ARTIS to Sardinia to be released in the wild later this year. The birds hatched in April and May last year in ARTIS. One young bird was cared for by a same-sex male griffon vulture couple. The other vulture is the offspring of two vultures who had been injured in the wild in Spain and – after having partially recovered – were admitted to ARTIS.
On 18 January 2019, Artis zoo reported (translated):
Early in the morning yesterday three young griffon vultures from ARTIS were transported to Sardinia. Here the vultures will get used to their new environment, before they will fly free later this year.
Road traffic victims successfully raise chicks
The young vultures hatched in ARTIS last spring. Three of the six parent vultures are from Spain and were unable to live in the wild due to a traffic accident. In ARTIS they were taken care of, recovered and they could form couples with other griffon vultures. The chicks that they have raised will be freed again in the wild. In this way they contribute to the conservation of the griffon vulture in Europe.
