Fhalacrocorax auritus, Double-Crested Cormorant Census a?id distribution The Double-crested Cormorant began nesting on the inner coasts of southern British Columbia and northern Washington about 40 years ago (Drent and Guiguet, 1961). Of the British Columbia colonies, Mandarte was the first to be discovered, thanks to the vigilance of W. Burton and the prompt verifica- tion by J. A. Munro (Munro, 1928). Later the colony on Ballingall was found, but judged older in origin (Munro, 1937). Aiandarte was thus the second colony to be established in the Province, but it is today by far the largest. Available counts for the Mandarte colony are given below; a more detailed listing with references will be found in Drent and Guiguet (1961: 25-26). 1927 1-3 pair, the first report 1935 5 pair 1936 9-11 pair 1942 15-20 pair 1945 23 pair in original group, total not certain 1953 145 pair total, three subcolonies (25, SS, 65) 1957-60 135-150 pair, in three subcolonies (see text).
