He does seem rather sad. I hope he/she was rehabilitated and released. But although I'd rather see animals back where they belong, I'm glad that some of the more seriously injured can serve in an educational capacity at some of these centers. In the wild they would not be able to defend themselves, so this life is the best for them and their situation. Good shot.
What a sweet face. I have mixed feelings about zoos. They have to have a lot of space, companionship and not look confined. Some are better than others. I detested the circus though...and clowns scared me.
