The LA Zoo used to have a really ugly bridge from the parking area to the zoo, but it was demolished when the new entrance complex was built with the zoo sign marquee that "can be seen from outer space" as Michael Dee described it.
Polar bears, giraffes, zebra, warthog, seals, wolves, bald eagles.... it's still quite a significant chunk. But Toledo wins extra points for having a bridge and a tunnel.The bridge at Toledo isn't technically the entrance but it might as well be, only a tiny portion of the zoo is on the entrance side of the bridge.
I would bet the geese are wild.Zoo America has a bridge connecting it to the amusement park. It goes over a river and there are often a lot of Canadian Geese in it, along with other waterfowl. Not sure if the zoo owns the waterfowl or if they are wild, could be either.
That is definitely the more probable situation.I would bet the geese are wild.
