John James Audubon by John Burroughs

“The chief of American ornithologists was John James Audubon. Audubon did not begin where Wilson left off. He was also a pioneer, beginning his studies and drawings of the birds probably as early as Wilson did his, but he planned larger and lived longer. He spent the greater part of his long life in the pursuit of ornithology, and was of a more versatile, flexible, and artistic nature than was Wilson. He was collecting the material for his work at the same time that Wilson was collecting his, but he did not begin the publication of it till fourteen years after Wilson’s death. Both men went directly to Nature and underwent incredible hardships in exploring the woods and marshes in quest of their material. Audubon’s rambles were much wider, and extended over a much longer period of time.” -Preface
