A hand-coloured engraving by John James Audubon, 'Plate 106 Black Vulture or Carrion Crow' showcases the artist's meticulous detail and scientific accuracy in depicting American birds in their natural habitats.

John James Audubon was a French-American ornithologist, naturalist, and painter, notable for his expansive studies documenting all types of American birds and for his detailed illustrations that depicted the birds in their natural habitats. His major work, *The Birds of America*, is a collection of 435 life-size watercolours of North American birds, published as a series of engravings between 1827 and 1838. Audubon's meticulous approach combined scientific accuracy with artistic flair, setting a new standard for ornithological illustration. He is considered one of the foremost naturalists of the 19th century. Plate 106, titled *Black Vulture or Carrion Crow*, presents a scene of two black vultures perched over the carcass of a deer. The vultures are depicted with careful attention to their plumage and anatomy, capturing their predatory nature. The composition is both scientifically informative and artistically striking, reflecting Audubon's skill in blending naturalism with aesthetic appeal. The background is minimal, focusing attention on the birds and their interaction with the environment.
