#45624 Arnold Böcklin (1827-1901)

The picture has something of this: people, man, water, nude, tree, recreation, two, woman, shirtless, reclining, group, Impressionism, wear, mammal.
Perhaps it’s a painting of a naked man holding a bird next to a naked woman with a bird on her arm and a bird perched on her shoulder, with a tree in the background.
