| Abstract | Cory’s Shearwater, Calonectris diomedea, is a pelagic seabird that winters in the waters off the state of Rio Grande do Sul in southern Brazil. Elsewhere, its diet is comprised mostly of fish and cephalopods, but dietary details out of the breeding season are unknown. The present study analysed the diet of Cory’s Shearwater along the coast of Rio Grande do Sul based on the stomach contents of 185 birds found dead during beach surveys between July 1997 and July 1998. Food items were classified taxonomically and non-food items were categorized. The taxa identified included the cephalopods Argonauta nodosa and Histioteuthis sp. and the fish Paralonchurus brasiliensis, Porichthys porosissimus, and Prionotus punctatus. Cephalopods were present in 97% of stomachs and fish in 33% of stomachs. Synthetic materials were found in 81% of stomachs. Our data corroborate the general ideas of Procellariiform diet during migration. The high amount of synthetic materials indicates the pollution of the marine environments of southern Brazil and we call attention to this situation. |

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.
