More photos from Santee Lakes

We were entertained by the coots, but weren't sure if it was courtship behavior or territorial.  I researched this and  have learned that it is territorial --  two males fighting, each defending his territory.  They kept at it for quite some time, and we noticed that every so often another coot would fly in and watch.  

 

















I'm wondering about an ID on this duck.  After looking at many different ID photos, I'm guessing it might be a young pied-billed grebe.  They breed at Santee Lakes I learned.
