Do you remember what species are not on regular display and only able to be seen during the presentations/shows? Also do they often do presentations and do you remember when the earliest ones begin?
I am trying to plan a trip to St Louis Zoo. World Bird Sanctuary is very close and they also open at 8 AM, so it looks like I can even visit before the zoo opens. But I first want to figure out if I could even be able to see their rarities in the early morning hours.
