How many were there, and did any other Indonesian collections have them? Unfortunately JAZA mislabeled some Japanese zoo’s gibbons as this species on the database, and I had to call the zoos in advance to confirm that they didn’t actually have it.
@RatioTile Not too sure of the ID on this one. I was told H. albibarbis by the keepers, but doesn't match up exactly. Although it's hard to find many/any images of females.
