During its stay Trasgu will be housed with an unrelesable vulture that will keep him company -until it can be replaced by a healthy one-, prior to the release.
Trasgu is the 15th black vulture to join the project in Alinya since 2007, as part of the re-introduction project in Catalunya. Two of these vultures were released by the method of hacking, and the other 12, with Trasgu to follow, were released from the habituation aviary.
