Yes they did. But given the trend in the program and recent Ungulate TAG recommendation to phase out, we will see. Its either they slowly phase them out (potentially sending breeding stock to interested non-aza parties) or they attempt to single handedly manage the population (with 30, space is not indefinite so a breeding halt will soon be necessary anyways) In my opinions the writings on the wall.
I love gaur one. They are one of my favorite ungulates but I do know an unsustainable program when I see one and I believe Bronx does as well. AZA can’t be managing 80 species of ungulate and hope that all populations are sustainable. It just hasn’t worked so sadly gaur who had little institutional support, have greater exhibit needs than many other species, and are notoriously difficult to work with compared to there preferred replacement.
