Spaniel Seizing a Bittern Jean-Baptiste Oudry (1686-1755)

The picture has something of this: bird, nature, wildlife, raptor, water, outdoors, feather, animal, wild, eagle, biology, river, predator, rock, hunter, beak, poultry, tree.
Perhaps it’s a painting of a bird and a dog fighting over a body of water with a bird in it’s mouth and another bird in the foreground.
