Breeding Ecology of Aechmophorus Grebes
About This Registration Clear Lake hosts a large population of breeding Western Grebes and Clark's Grebes, which Dr. Hayes has been monitoring for the Redbud Audubon Society since 2010. Funded by oil spill mitigation funds to compensate for damage caused by the S.S. Jacob Luckenbach, the project focuses on monitoring the reproductive efforts and success of the grebes, protecting their nesting colonies, and educating the public. Dr. Hayes will provide an analysis of how the grebes' reproductive efforts and success are affected by variable water levels. He will also provide information on their natural and anthropomorphic threats plus some novel insights on their breeding biology, such as hybridization, nocturnal copulation, intraspecific egg destruction, communal egg dumping, and use of nests by other species of vertebrates. Floyd E. Hayes, Ph.D., is a professor of biology at Pacific Union College in Napa Valley, California. Dr. Hayes specializes in the ecology, behavior and biogeography of birds and other organisms and has published the results of field research in 14 different countries. While an undergraduate student, Dr. Hayes took off a year to teach in an elementary school on the island of Kosrae in Micronesia. He worked for three years as a vertebrate biologist for the US Peace Corps, based in the National Museum of Natural History of Paraguay. He also taught biology for nine years at Caribbean Union College (now the University of the Southern Caribbean) and the University of the West Indies in Trinidad and Tobago, and spent a year working as a wildlife biologist for the Division of Fish and Wildlife in St. Thomas, US Virgin Islands. Dr. Hayes was the editor in chief of Journal of Caribbean Ornithology from 2005-2013.
