Together these results show a clear avoidance response of the killer whales to the sounds of long-finned pilot whales. 📷 Katarína Klementisová, Curt Hanson

Pilot whales and killer whales swimming very fast.

And group members moved closer together and moved in a more aligned way.

They often initially increased their calling rate, followed by a clear decrease.

Killer whales responded to pilot whale sounds by switching to a travelling behaviour, increasing speed and moving away from the sound source.

We conducted playback experiments to tagged killer whales. We played sounds of long-finned pilot whales and a noise control. Killer whale responses were investigated using a state-dependent model, as well as GEEs to test horizontal movement, acoustic, and group-level responses. 📷 Tatiana Marchon

Pilot whales are known to exhibit a mobbing-like behaviour towards killer whales. Acoustic signals are important in mobbing behaviours. Previous studies have shown that pilot whales are attracted to the sounds of killer whales and increase their vocalisation in response. Listen to an example 🔈🎧⬆️
