Sálim Moizuddin Abdul Ali (12 November 1896 – 20 June 1987) was an Indian ornithologist and naturalist. Sometimes referred to as the "birdman of India", Salim Ali was among the first Indians to conduct systematic bird surveys across India and his bird books helped develop ornithology. He became the key figure behind the Bombay Natural History Society after 1947 and used his personal influence to garner government support for the organisation, create the Bharatpur bird sanctuary (Keoladeo National Park) and prevent the destruction of what is now the Silent Valley National Park. He was awarded India's second highest civilian honour, the Padma Vibhushan in 1976.
On his return to India in 1930, he discovered that the guide lecturer position had been eliminated due to lack of funds. Unable to find a suitable job, Salim Ali and Tehmina moved to Kihim, a coastal village near Mumbai. Here he had the opportunity to study at close hand, the breeding of the Baya Weaver and discovered their mating system of sequential polygamy. Later commentators have suggested that this study was in the tradition of the Mughal naturalists that Salim Ali admired and wrote about. A few months were then spent in Kotagiri where he had been invited by K M Anantan, a retired army doctor who had served in Mesopotamia during World War I. He also came in contact with Mrs Kinloch, who lived at Longwood Shola, and her son-in-law R C Morris, who lived in the Biligirirangan Hills. He then discovered an opportunity to conduct systematic bird surveys of the princely states that included Hyderabad, Cochin, Travancore, Gwalior, Indore and Bhopal with the sponsorship of the rulers of those states. He was aided and supported in these surveys by Hugh Whistler who had surveyed many parts of India and had kept very careful notes. Interestingly, Whistler had initially been irritated by the unknown Indian. Whistler had in a note on The study of Indian birds mentioned that the long tail feathers of the Greater Racket-tailed Drongo lacked webbing on the inner vane. Salim Ali wrote that such inaccuracies had been carried on from early literature and pointed out that it was incorrect on account of a twist in the rachis. Whistler was initially resentful of an unknown Indian finding fault and wrote "snooty" letters to the editors of the journal S H Prater and Sir Reginald Spence. Subsequently Whistler re-examined his specimens and not only admitted his error but became a close friend.
Whistler also introduced Salim to Richard Meinertzhagen and the two made an expedition into Afghanistan. Although Meinertzhagen had very critical views of him they became good friends. Salim Ali found nothing amiss in Meinertzhagen's bird works but later studies have shown many of his studies to be fraudulent. Meinertzhagen made his diary entries from their days in the field available and Salim Ali reproduces them in his autobiography:
