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 in three-part series on the Moghul emperors as naturalists. 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, widow of BNHS member Angus Kinloch who lived at Donnington near Longwood Shola, and later her son-in-law R C Morris, who lived in the Biligirirangan Hills. Around the same time he discovered an opportunity to conduct systematic bird surveys in the princely states of Hyderabad, Cochin, Travancore, Gwalior, Indore and Bhopal with the sponsorship of their rulers. He was aided and supported in these surveys by Hugh Whistler who had surveyed many parts of India and had kept very careful notes. Whistler published a note on "The study of Indian birds" in 1929 where he mentioned that the racquets at the end of the long tail feathers of the greater racket-tailed drongo lacked webbing on the inner vane. Salim Ali wrote a response pointing out that this was in error and that such inaccuracies had been carried on from early literature and pointed out that it was incorrect observation that did not take into account 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 wrote to Ali on 24 October 1938:
