For more than 50 years, Dr J. Bruce Falls has been active in protecting Canada’s natural landscapes. As President of the Federation of Ontario Naturalists, Dr. Falls was instrumental in the 1962 founding of The Nature Conservancy of Canada (NCC). The NCC has helped to protect more than one million hectares of ecologically-significant land nation-wide. Dr. Falls was a professor of Zoology at the University of Toronto for 35 years, where he helped initiate field courses because he believed that contact with nature stimulated students’ interests. As the author of more than one hundred scientific publications, he is known for his work on small mammal population fluctuations in Algonquin Park, and his research on dimorphism in White-throated Sparrows. He was a pioneer in the study of bird song and its relation to territorial behaviour. A member or fellow of several scientific societies and a past president of the Society of Canadian Ornithologists, Dr. Falls was co-chair of the conservation panel of the International Biological Programme for Ontario, and a founder of Bird Studies Canada
