The population of the Greater Sandhill Crane (Grus canadensis tabida) wintering in the Central Valley was listed as a sensitive species by the U.S. Fish and Wildlife Service in 1982, and as a threatened species by the State of Californiain 1983. Many of these cranes breed in northeastern California. In 1988, I surveyed the species’ California breeding range, locating nests and following up on the fate of selected pairs.
