Individual, ecological, and anthropogenic influences on activity budgets of long-finned pilot whales
Time allocation to different activities and habitats enables individuals to modulate their perceived risks and access to resources and can reveal important trade?offs between fitness?enhancing activities (e.g., feeding vs. social behavior). Species with long reproductive cycles and high parental inv...

Time allocation to different activities and habitats enables individuals to modulate their perceived risks and access to resources and can reveal important trade?offs between fitness?enhancing activities (e.g., feeding vs. social behavior). Species with long reproductive cycles and high parental investment, such as marine mammals, rely on such behavioral plasticity to cope with rapid environmental change, including anthropogenic stressors. We quantified activity budgets of free?ranging long?finned pilot whales in order to assess individual time trade?offs between foraging and other behaviors in different individual and ecological contexts, and during experimental sound exposures. The experiments included 1-2 and 6-7 kHz naval sonar exposures (a potential anthropogenic stressor), playback of killer whale (a potential predator/competitor) vocalizations, and negative controls. We combined multiple time series data from digital acoustic recording tags (DTAG) as well as group?level social behavior data from visual observations of tagged whales at the surface.
