text: We know, for example, from work done in the 1930's by John Emlen at Cornell University that approximately 25,000 crows were gathering in a roost near Auburn, NY in the winter of 1932-33, and that a large roost was present in 1911-12 (Emlen, J. T., Jr., 1938, Midwinter distribution of the American Crow in New York State, Ecology 19: 264-275).
