Hi Napper, have you seen any Royal terns or Black skimmers? In the past I've seen quite a few of these around Port Charlotte and neighbouring beaches. Gasparilla island esp. good for the terns. A good spot to go at sunset is Ponce de Leon park at Punta Gorda, I've seen various heron here.
A great place is the Venice Rookery (not easy to find but worth the effort.) North on US 41, take 1st left on Annex after Jacaranda.
