Abstract
Killer whale call repertoires can provide information on social connections
among groups and populations. Killer whales in Iceland and Norway exhibit
similar ecology and behavior, are genetically related, and are presumed to have
been in contact before the collapse of the Atlanto-Scandian herring stock in
the 1960s. However, photo-identification suggests no recent movements between
Iceland and Nor- way but regular movement between Iceland and Shetland.
Acoustic recordings collected between 2005 and 2016 in Iceland, Norway, and
Shetland were used to undertake a comprehensive comparison of call repertoires
of Northeast Atlantic killer whales. Measurements of time and frequency
parameters of calls from Iceland (n = 4,037) and Norway (n = 1,715) largely
overlapped in distribution, and a discrimi- nant function analysis had low
correct classification rate. No call type matches were confirmed between
Iceland and Norway or Shetland and Norway. Three call types matched between
Iceland and Shetland. Therefore, this study sug- gests overall similarities in
time and frequency parameters but some divergence in call type repertoires.
This argues against presumed past contact between Icelandic and Nor- wegian
killer whales and suggests that they may not have been one completely mixed
population.
