Many of Burroughs' essays first appeared in popular magazines. He is best known for his observations on birds, flowers and rural scenes, but his essay topics also range to religion, philosophy, and literature. Burroughs was a staunch defender of
Walt Whitman and
Ralph Waldo Emerson, but somewhat critical of
Henry David Thoreau, even while praising many of Thoreau's qualities. His achievements as a writer were confirmed by his election as a member of the
American Academy of Arts and Letters.
