A banner about the drills which implies that they will be coming in September. The drills can be seen inside their house, while their island is still undergoing construction (the banner might be saying that their island will be ready for them by September). A plan drawing is included on the banner, showing the area where the animals' indoor viewing is. Apparently, the Chilean flamingos will be moving down to this area, as 'flamingo habitat' is mentioned on the plan.
Have there been any new species after them? I know that mountain chicken frogs were brought in 2021, but I believe that they had gone out of them the year before rather than being a truly new species.
