This little one, with his legs in those positions, looked like he was dancing. Pretty little sandpiper of some kind. Very greyish so using only Shadow Violet as the body color.
No drawing, just painted in the background water around him, leaving some whites where he would be, then painted him. More to finish to darken up some areas and delineate the water from the shore (he's right on the edge).
I think this one is called a Red Knot, brown in the summer, but grey in the winter. I really don't know the wading birds all that well so to me they are all either egrets, herons, pelicans or sandpipers (although there are many different sandpipers).
Painted on 140# cold press Fabriano watercolor paper.
