Gradually during recent years a new body of knowledge has developed showing that some chemicals in food and water can mimic hormones and disrupt the development of living things like fish, birds, and mammals, including their sexual development. In some cases, the effects on wildlife have been dramatic. For example, male herring gulls on Lake Ontario, exposed to DDT and other organochlorine compounds, developed female sex organs. Female-female pairing has been observed in herring gulls on Lake Michigan and on Santa Barbara Island, California.
