My sister and I visited the zoo while in Birmingham. I am a kid at heart and I ABSOLUTELY LOVED seeing all of the animals. I was a little surprised to find that there were no bears at the zoo. And also a little disappointed that all of the animals were caged. I guess I was comparing it to the Atlanta Zoo, where the animals are allowed to roam around in more of a "natural habitat."
Patrons are not allowed to bring food into the zoo because the signs say that food is for sale inside the zoo. However, none of the food places were open. The signs said they would reopen in the spring. I would suggest bringing in a few snacks if you visit.
