Our Bird Comrades is an 1897 book of popular ornithology by Leander Sylvester Keyser (1856-1937), the American clergyman and nature writer who brought birdwatching to a wide readership in the decades before field guides. Keyser writes as a companionable observer, walking the reader through woods and fields to meet the warblers, thrushes, and sparrows by habit and song. His books belong to the nature-study movement that taught Americans to look closely at the living world around them. Free PDF download available on BDeBooks.
