Thirty years of herd focal follows reveal the functions of important habitats identified for the endangered St. Lawrence Estuary beluga

Endangered Species Research
Identifying habitat functions is crucial for understanding how endangered populations such as the St. Lawrence Estuary (SLE) beluga Delphinapterus leucas use their environment, and for guiding effective conservation measures. Often, the only way to infer

Beluga, Delphinapterus leucas, Group Sizes in Cook Inlet, Alaska, Based on Observer Counts and Aerial Video [PDF]

, 2000
Belugas, Delphinapterus leucas, groups were videotaped concurrent to observer counts during annual NMFS aerial surveys of Cook Inlet, Alaska, from 1994 to 2000. The videotapes provided permanent records of whale groups that could be examined and compared

Do belugas send sound cues? -Experimental verification of blindfolded imitation among beluga-

International Journal of Comparative Psychology
Dolphins are able to successfully coordinate their behavior using audio signals. Therefore, the current study tested whether or not belugas can use sound to exchange information in a cooperative task and verified the mechanisms of the transmission of information during trials. The subjects are two male belugas, Nack and Duke. Nack was trained to rotate
