Which park should I go to in St. Petersburg, FL?

I will be going to St. Pete for a few days during the weekend. I have a full itinerary including the Dali museum, Sunken Gardens, Weedon Island, Chihuly Collection at Morean Arts Ctr, and touring historic Main Street. I am torn between visiting Sawgrass Lake Park or Boyd Nature Preserve. I love taking pix of wildlife. Which park would is prettier?
