I was lucky while visiting an area that had quite a few coots that I came across this pair. They were nuzzling each other at first . From there they procceded to do this little syncronized dance together. Totally awesome. Totally in sync with each other. I expect it is a mating dance. They then strolled off together into the water were one proceeded to preen itself on the beach before going off with its mate for a swim. Very cool. Timing is everything for sure.
