Echolocation and foraging behavior of a Baird’s beaked whale

In collaboration with Alison Stimpert at the Moss Landing Marine Laboratories, we published the first multi-sensor tag data and controlled exposure experiment of a Baird’s beaked whale (Berardius bairdii). Baird’s beaked whales represent species in the family Ziphiidae, an enigmatic group of toothed whales that are characterized by their extreme deep diving capabilities. Because they exhibit such long, deep dives, the opportunity to tag these whales or experimental studies is extremely rare. Nevertheless, the diving behavior of beaked whales and their response to anthropogenic sounds has been a high priority for researchers given apparent sensitively to mid-frequency sonar. These data increase our understanding of a species which is poorly understood, and complements other recent studies that test the response of cetaceans to anthropogenic sounds.
