It's the Detroit Zoo. We love going to the zoo and are members We spent literally all day at the zoo. We saw everything, at least once.
They had a redfoot in the little sanctuary area with the sloth (in another area though) and I guess he kept coming up on the platform where people walk and ramming them. The keeper lady said she was shocked and I told her about how bettuce will run halfway across the yard to bite my lab who is laying there not bothering anyone. She had no idea tortoises could be territorial.
Oh and we saw some pancake tortoises having adult time. I tried to take pics but my flash apparently protected their modesty.
