Bird hunting food

This bird stood by the northwest end of the pond awhile, then crouched, half-hidden, down in it. Then it climbed out and walked jerkily (on jointed legs) south, then east--off into the distance. Its neck had an amazing range of shape and motion, shrinking into a small, tight "s", then angling up and out long, almost into a straight line. It appeared to have a black stripe across the side of its head, but that stripe flew back a little loose when it was walking fast. It was the only bird I saw there, mid-afternoon. It may be a blue heron? Not sure.

Graphite and watercolor. This small Cachet sketchbook paper doesn't take much water. I use it mostly with dry media, to practice drawing people.
