Called the ‘Birdman of India’, ornithologist Dr Salim Ali (1896–1987) pioneered systematic bird surveys across India. He wrote the largest number of books on ornithology. Some of his important books are: Indian Birds (1941); Birds of Kutch (1945); Indian Hill Birds (1949); Birds of Travancore and Cochin (1953); Birds of Sikkim (1962); Handbook of the Birds of India and Pakistan in 10 volumes (1968-74); Pictorial Guide to the Birds of the Indian Subcontinent (1983); and his autobiography, Fall of a Sparrow (1985).
