I saw the big green clowns up in a palm tree at Fort Desoto near the fishing pier. I heard them first. That loud scream can be heard across the park.The black capped (or nanday) parakeets were eating something up in the tree.
Many of them were flying down and feeding on the wildflowers growing next to the pier. It was funny to watch them holding the plant with their feet. They kept their eye on me but otherwise kept eating.
Some of them would fly back up in the tree with their snack and eat there.
