Grey Seals and Drones

Grey seals (Halichoerus grypus) are found on both shores of the North Atlantic. They feed a variety of fish, mostly benthic or demersal species. During the winter months, female grey seals in Nova Scotia haul out on beaches such as Hay and Saddle Islands to start pupping. Females usually give birth about a day after coming

All bays are not created equal: Predicting spinner dolphin resting habitat

Coastal spinner dolphins in Hawaii, and elsewhere in the world, rely on sheltered bays for rest. These inshore locations provide an opportunity for dolphins to recover energetically and cognitively during daylight hours after extended nighttime foraging bouts, while minimizing predation risk. This behavioral trait often beings them into close contact with humans involved in dolphin-based
