Cover image: Foraging Laysan Albatross (Phoebastria immutabilis). Albatrosses soar over vast expanses of the ocean to search for food. Large olfactory bulbs in the wandering albatross (Diomedea exulans) suggest that the birds locate prey and carrion by scent. In their article on pages 4576–4581, Nevitt et al. report how albatross flight paths, obtained by GPS tracking, and feeding logs, recorded by stomach temperature sensors, confirm the scent hypothesis.
