CJ Ralph, Sc.D., KBO Research Advisor

CJ Ralph is a Research Wildlife Biologist at the USDA Forest Service's Redwood Sciences Laboratory in Arcata, California. Additionally, CJ is co-chair of the Monitoring Working Group of Partners in Flight, chair of the North American Banding Council, and a Faculty Associate in the Department of Biological Sciences at Humboldt State University.

CJ co-founded Point Reyes Bird Observatory (now Point Blue Conservation Science) and, more recently, helped start the Klamath Bird Observatory.

CJ's early research centered on bird migration and orientation. CJ studied the behavioral ecology of endangered forest birds in Hawaii for five years before moving to Arcata in 1981 to begin work with the USDA Redwood Sciences Laboratory. CJ's two principal research focuses for Redwood Sciences Laboratory have been landbird monitoring (involving censusing and constant effort mist-netting) and the study of the Marbled Murrelet, an endangered seabird that depends on old growth forests for nesting.

CJ also has been directing research at a bird monitoring station in Costa Rica since1994, and he conducts research on an island off New Zealand involving the monitoring and reintroduction of native birds.
