does the miami zoo kick everyone out after closing?

According to its website, it is open until 5 with the last entry being at 4.  So you can get in until 4, but have to leave by 5.

Yes, when they close, you have to leave.

It means that everyone is supposed to leave by then.  Everyone really needs to be gone before it gets dark, because there aren't lights everywhere.  And it's a big zoo and takes a long time to get from some parts of it to the exits, so they will start making you walk to the exit at 4 so that you get there before dark.

People won' be allowed to enter after a certain period, then they'll start herding people out as they approach closing time.

Closing means they kick you out.  No one probably admitted after 3
