caption: The image shows a painting of a Cooper's Hawk perched atop a tree branch, with the text "Aldr, Esmerillon, 1858" written underneath. The hawk is depicted in great detail, with its wings spread wide and its head turned slightly to the side. Its feathers are a mottled brown and white, and its eyes are a deep yellow. Its beak is a yellowish-orange color and its talons are gripping the branch tightly. The background of the painting is a light blue sky with white clouds.
