I forgot to mention how I walked passed by or didn't pay attention at the birds in my visit to Berlin. So I may or may not have seen the Andean and James's flamingos, nocturnal curassow, and channel billed cuckoo.
Beating my chest in front of a gorilla, he actually ran at the glass and tapped in Lincoln Park Zoo. Well slammed against it aggressively.
The last time I would ever do that one. I even witnessed a child do that a few years ago. History repeating itself.
