英文摘要

The strategy used by the intraspecific brood parasite, the grey starling, Sturnus cineraceus (Temminck) and the degree to which this strategy reflected the sources of mortality for parasite eggs were examined. Approximately 74% of all parasite eggs failed to produce young that survived to fledglings. Most of this mortality was due to two factors: (i) laying in a nest that had been deserted by a host during its nesting cycle (19%); and (ii) mismatched timing of laying in the host’s nesting cycle (38%). It is important for parasites to select a suitable host in order to avoid this mortality and increase their reproductive success. However, grey starlings did not select hosts on the basis of nest location, host characteristics, or laying date. Lack of attention to these factors implies a failure on the part of the grey starlings to recognize cues that could direct them to select host nests that would provide the best environment for their eggs. Although some egg loss and egg replacement occurred before clutch initiation by hosts, no evidence was found that parasitic birds removed host eggs after clutch initiation by hosts. These results suggest that parasites did not adopt a successful strategy for enhancing the survival rate of their own eggs.
