@Summer Tanager Many of the geese at Pairi Daiza, although wild or feral, are actually very habituated to humans and allow humans quite close to them or come close to humans themselves. And geese are already known for being quite bold, if not often aggressive birds.
Actually some of the greylag geese are known to scavenge around the watermill area (small restaurant selling stuff like sandwiches and cakes) for food scraps, and are sometimes aggressive to humans there. I have also seen some Canada and barnacle geese on the road in the fallow deer area in The Last Frontier, both during the day and at nighttime.
