We saw quite a few Red-breasted Mergansers in with the Pelicans, Roseate Spoonbills and Cormorants. They were spending a lot of time diving looking for a meal, scooting around through the other wading birds in the water. This one came on shore after it was done diving around for 20 minutes and was flapping its wings to dry off.
