AbstractIn 1980, whales alternated periods of socializing with periods of feeding in several different ways: near the bottom, in the water column, with some socializing and skim feeding. In 1982, almost all activity appared to be feeding in the water column. In 1980, most whales studied were in water only 10-40m deep. In 1981 they were farther from shore and in >20m depth, and in 1982 long (10-30 min) dives were common in depths of 40-600m. Variability in distribution and behavior presumably was related to availability of prey. During near-surface skim feeding, whales often associated in V-shaped or echelon formations, with up to 14 animals staggered behind and to the side of each other, all moving in the same direction at the same speed, with mouths wide open. Such coordinated movement may increase the efficiency of feeding on concentrations of small invertebrates.-from Authors
