| Abstract | 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. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
