In the section for Fota, it mentions in the animal inventory that the male drill died sadly. I don't think the drills have ever bred in the three years they've been in Fota, so I wonder if they're planning to get a new male in if they haven't already. One of the Francois' langurs is also said to have died.
Good to know!A new drill arrived a few months back.
