T. S. Shulezhko and V. N. Burkanov (2008): Stereotyped acoustic signals of
the killer whale Orcinus orca (Cetacea: Delphinidae) from the Northwestern
Pacific. Russian Journal of Marine Biology, 34(2), 118-125.
Abstract: In this paper the classification of the discrete calls of killer
whales recorded in the Northwest Pacific is presented. It was shown that
most of the calls can be divided into 20 discrete types easily distinguished
by ear. The frequency parameters of the sounds made the maximum contribution
into discrimination between call types, while their temporal parameters
turned out to be less significant. The repertoires of stereotyped calls of
killer whales from Chukot, Kamchatka, and the Commander and Kurile Islands
were similar, due to the presence of shared types of calls. The greater the
distance between the above-mentioned regions the fewer calls were shared by
the resident killer whales. High vocal activity and the phenotypic features
of the surveyed killer whales implied their attribution to the resident
ecological type.
