watching and waiting
Whenever I go for a walk on the beach at the park on Lido Key there are always a few people fishing. There is a place where the current speeds up to pass between Lido Key and Siesta Key, and apparently there is good fishing at that location.
Standing behind each person is at least one Heron. I have never seen any of the people fishing throw a fish to the Herons but I guess they must since these guys are always there waiting for a meal.
