Horses And Ducks By A River John Frederick Herring (1795-1865)

The picture has something of this: mammal, horse, cavalry, farm, animal, livestock, hayfield, field, grass, pasture, equestrian, mare, domestic, stallion, rural, equine, herd, mane, agriculture, grassland.
Perhaps it’s a painting of a group of horses standing next to each other in a field with a thatched roof and a few dead birds on the ground.
