Wilson's storm petrel (Oceanites oceanicus) characteristically feeds by ' hovering' over the water surface, but its technique for this is unlike that of other flying vertebrates. The kinematics and aerodynamics of this ' hovering' flight were investigated to determine the possible sources of lift; various nonaerodynamic sources of lift were discounted. It is suggested that the storm petrel soar...
متن کاملAre Commercial Fishers Risk Lovers
Empirical studies of fishers’ preferences have found that most fishers are risk-averse, while expected-utility theory predicts risk neutrality even for sizable stakes. We test this prediction using data from a stated choice experiment with Swedish commercial fishers. Our results show that almost 90% of the respondents do not behave as expected-utility maximizers. 48% of the fishers can be broad...
متن کاملA burrowscope for examining petrel nests in burrows
This report describes the development and refinement of a burrowscope that is reliable and robust enough to withstand arduous field conditions crucial for obtaining accurate data on sooty shearwater (Puffinus griseus) burrow occupancy and breeding success. The burrowscope consists of a miniature camera and infra-red lights mounted on a three metre length of hose through which images are project...
