Great snipe and bullfinch. Etude Vasily Tropinin (1776-1857)

The picture has something of this: bird, wildlife, reproduction, two, water, poultry, swimming, daylight, biology, mammal, side view, fish, nature, outdoors, invertebrate.
Perhaps it’s a close up of a painting of a bird on a piece of wood with another bird on it’s back and another bird in the background.
