Rock hyraxes and guineafowl in a walkthrough aviary.
That day was very insufferable, as dumbass zoo visitors kept the two doors to the aviary open at once! And they're excuse for being uneducated idiots is "Oh, we're village people!".
And don't even get me started on the aardvark...
Some species of Lemur.
The day I went, the guests were especially insufferable; they made so much noise that all the lemurs just hid in the trees! >:C
