This Anhinga was up there for a long time doing a lot of preening. Don't quite understand why, as it will be right back in the water in just a few minutes.
The feathers become water logged which allows them to dive deeper by preventing air bubbles from getting trapped underneath the feathers. For that reason they need to be dry before they go down again (says google)
