Abstract

Decreased nest success and elevated levels of nest predation have been linked to changes in landscape configuration and increased edge. Using radiotelemetry and artifical nests, we studied the ranging and nest-predation behavior of the Steller's jay (<em>Cyanocitta stelleri</em>) in the managed forests of western Washington. Steller's jays did not appear to use a specialized search strategy to find nests, although they were ca[ab;e pf performing area-restricted serching for other food items. By equating relative abundance of Steller's jays with nest predation risk, managers can map predation risk onto the landscape at the scale of the management unit.
