Very Very Last of the Old Birdlover's Watercolors: Hooded Merganser

Truly the very last few today from a great bunch of old naive watercolor of birds done by someone long ago who was quite serious about his birds! Each and every one of them a charmer I think, this one portraying a proud Hooded Merganser, with especially good hand-painted attribution under the patch of blue water at bottom left.

7 1/16" x 5 1/6" and in good condition, with a bit of erased pencil outline to the right of the head and right leg, which just makes me like it more.
