Marine mammals / Historical acoustic study
A shared song can change across years
Original study year 1985 · Note reviewed 2026-10-04
Across 163 songs sampled near Bermuda, songs within a year were similar while their content changed across years. The series covers 13 sampled years between 1957 and 1975.
What we reviewed · Selected evidence reviewed
Indexed 1985 publisher abstract and 2017 review abstract; full methods, spectrograms and original audio not reviewed.
Not yet independently reviewed by a scientific specialist.
What this does — and doesn’t — establish
Seasonal sampling is not a continuous 19-year recording. Changing structure does not reveal translated meaning; the later review discusses unresolved functions of song in the mating system.
What we can build on
Test models across years as well as individuals: a recording date can change what a pattern means.
