obtained from opportunistic underwater video recordings

Abstract
Encounters of humans with wild animals should be investigated before
commercial operations will be established. This study describes
interactive behaviours of wild and unhabituated Norwegian killer whales (Orcinus orca)
during close encounters with video-filming human divers and
snorkellers. Swimmers followed a code-of-conduct to minimise
disturbance. Interactive behaviours initiated by cetaceans and shown in
close proximity to human swimmers can be described using an ethogram.
Such a behavioural catalogue provides baseline data for managing
in-water encounters. This study uses opportunistic underwater video
recordings. Videos were scanned for interactive behaviours and their
relative occurrence was measured. In total, eight interactive behaviours
were found that are considered to be exclusively affiliative in nature.
The most frequent behaviours were ‘calling’ [M = 0.74] and ‘eye contact’ [M = 0.67].
No aggressive behaviours were found. The present results facilitate the
first description of interspecific killer whale behaviours occurring
during in-water encounters with snorkellers and divers which is
essential to manage interactions properly in the future.
