Peasants Under the Trees at Dawn, Morvan c.1840-45 Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: tree, wood, nature, outdoors, landscape, water, leaf, environment, park, rock, scenic, river, flora, daylight, summer, recreation, mountain, sky.
Perhaps it’s a painting of a group of people in a wooded area next to a building and a tree with a red bird perched on top of the tree.
