Datlaf Vaughn (Chip) Weseloh has studied the ecology of colonial waterbirds for more than 30 years. He received his M.Sc. from Michigan Technological University in 1969 for a study of the effects of heron excrement on the herbaceous vegetation at a breeding colony, and his Ph.D. from the University of Calgary in 1976 for studies of the urban ecology of Ring-billed, California, and Franklin's gulls. He was Curator of Ornithology at the Provincial Museum of Alberta for 2 years before joining the Canadian Wildlife Service in 1978. He has spent the last 20 years working on the Great Lakes, where he is involved with monitoring levels and effects of toxic chemicals in colonial waterbirds.
