Hello Ontbirders It is with great sadness that I report the passing of Stewart D. MacDonald, Canadian Ornithologist, at age 83 on September 10, 2010. He was born April 22, 1927 in Bayhead, Nova Scotia. Stu began his career as a technician in behavioral science at the National Museum of Canada in Ottawa, now the Canadian Museum of Nature. He later attended the University of Iowa and returned to the museum in Ottawa as Assistant Curator of Ornithology. Stu was an accomplished artist and prepared the line drawings and maps in “The Birds of Canada” (Godfrey 1966, 1986). He spent much of his career studying Arctic birds including Ross's Gull and Ivory Gull. He retired in 1988 as Curator of Vertebrate Ethology at the Canadian Museum of Nature. Stu received the Massey Medal of the Royal Canadian Geographical Society in 1992 for his distinguished work as an Arctic explorer and ornithologist specializing in animal behaviour. He was generous with his time and vast knowledge of bird behaviour. Stu was a mentor to many birders and will be remembered with great fondness.
