Prairie Falcons Nest on an Artificial Ledge
Abstract
Four days during fall 1978 were needed to measure, construct, and install an artificial nesting ledge on a historical Peregrine Falcon nesting cliff in the Mendocino National Forest, California. The platform was constructed of steel with rock nesting material added onto it. Expansion bolts inserted into predrilled holes held the ledge in place. Prairie Falcons laid four eggs on the artificial ledge in April 1979. Two young hatched in May and fledged from the ledge in June 1979.
