Pied Billed Grebe
Certainly not a rare bird but they are fun to watch. They don’t seem as shy as some other birds, so I often have time to wait for good lighting, a better pose, etc.
I don’t think I have ever seen one actually in the air flying but I do see them “scooting” across the surface, leaving a wake behind them.
The “Pied” part of Pied Billed indicates a black band on the bill so I’m guessing that this guy is still young.
