Douglas Dewar (28 May 1875 - 13 January 1957) was an ornithologist and British civil officer in India who produced several books about Indian birds. He published widely in publications like The Madras Mail, Pioneer, and The Times of India, as well as periodicals like the Civil and Military Gazette and Bird Notes. He became an outspoken anti-evolutionist and co-founded the Evolution Protest Movement. Douglas was born in London, where his father, a physician, practiced on Sloane Street and in Hampton Wick. Before joining the Indian civil service in 1898, he studied natural science at Jesus College, Cambridge. Dewar married Edith Rawles, the daughter of Alfred Rawles, on March 7, 1902 in Bombay. From 1921 to 1924, he was appointed Accountant General in Punjab. Dewar, on the other hand, specialized in ornithology and produced numerous volumes about the birds of India. In his book Birds of the Plains, he emphasized the study of birds in the field. "There are two kinds of humans in the ornithological world. There are those who study nature inside the museum with a microscope and scalpel, and those who live to observe and study birds in the open."
