Selectivity of harvest influences harvest sustainability because individuals with different characteristics contribute differently to population growth. We investigate the effects of selection based on chick weight on a traditional harvest of the sooty shearwater Puffinus griseus by Rakiura Maori in New Zealand. This research was funded by a New Zealand Foundation for Research Science and Technology grant to Rakiura Maori and by the US Environmental Protection Agency (R-82908901–0).
