SUMMARY

PHILLIPS, C.M. 2000. Publications and theses on Antarctic and sub-Antarctic birds, 1996. Marine Orni- thology 28: 101–104.

A total of 106 scientific publications and theses on Antarctic and sub-Antarctic birds for 1996 is listed by the author. This annual list is produced on behalf of the Bird Biology Subcommittee of the Scientific Com- mittee on Antarctic Research (SCAR) Working Group on Biology as a service to marine ornithologists.
