Orcas typically congregate in much smaller groups, so the presence of such a large pod of orcas naturally raised some concerns.
So, why are they all gathered here?
The first theory was that they were members of a large extended family. To see if this was true, researchers listened to the orcas’ cries to one another.
Orcas from the same family often communicate in the same dialect. However, after a quick listen, it became clear that there were numerous dialects, implying that they are all from different families.
So, rather than a single large pod, there are several pods converging in this location, which is unusual for orca behaviour.
Could they have met with the intention of mating?
The breeding techniques of orcas are closely guarded secrets. We do know that they prefer to mate in warmer waters and during the spring. As a result, this video was shot in winter, which appears to be the wrong season for romance.
What about the possibility of a feeding frenzy?
In the video, there are a lot of birds circling overhead, which could indicate that there is a lot of food down below. The fish is most likely herring, a favourite of orcas in this part of Norway. However, there is no tail slapping in the video, making it appear that they are not herding them.
Instead, fishing boats can be seen in the distance, and they frequently breach the nets and steal fish for themselves. These sophisticated creatures have heard the sound of fishing boats and have gathered in anticipation of food.
