A 2023 analysis of endangered Cook Inlet belugas classified 1,633 vocalizations into 1,264 whistles (77 percent), 354 pulsed calls (22 percent), and 15 combined calls (1 percent), producing a catalogue of 41 call types. Automated classification methods agreed substantially, but not perfectly, with human classification.[1] Differences between catalogues can reflect genuine population variation as well as equipment, sampling, and analytical choices. A call-type number is therefore an output of a study, not a final count of everything a beluga can say.
