Worth the dip? Polar bear predation on swimming flightless greater snow geese and estimation of energetic efficiency

As sea-ice cover is shrinking, polar bears (Ursus maritimus, Phipps, 1774) face decreased access to seals, their primary prey, resulting in a greater dependence on terrestrial food sources. Whether polar bears can benefit from these terrestrial food sources, however, depends on their ability to find...
