At an early age, Audubon developed an interest in nature and drawing. He spent time exploring woods and making drawings of birds before devoting himself to his ornithological and zoological interests. When he took his drawings to a British publisher in 1826, his genius was immediately recognized. He published The Birds of America, which was issued in five volumes as Ornithological Biography.
