Along the brackish water at the mouth of the Tortuguero River, a male Anhinga (Anhinga anhinga) did a strange little dance as our boat floated past. I’ve no idea quite why the bird was flapping is silver-striped wings, though it was fun to see and photograph. Female Anhingas have a buffy brown neck and head instead of shiny black.
