Although I'm scared of bird (I suffered a vicious peacock attack as a child (seriously)), this place was pretty cool.
We just happened to arrive as one a raptor presentation was beginning. Seeing a presentation is a must (the trip would have not been as good without it). The woman doing the presentation brought out a number of birds and told us lots of interesting info about them.
After that, we just walked around to the different cages and checked out the other birds. If you want to take pictures, bring a camera with a zoom lens (I couldn't get close enough for my iPhone pictures to be very good).
