We set sail for the downstream sector, where we regularly come into contact with herds of males. We cross paths with Splash near the north shore. It is in a herd of 30 belugas, mostly white adults and a few young grays. After an hour of monitoring, the herd grows larger and now numbers about 40 individuals.
The animals are very active. Some belugas poke their heads above the surface as if to spy on us, others raise their tails out of the water. We can hear all sorts of vocalizations. A group of six individuals breaks rank with the rest of the herd, dozing off at the water surface. Then they begin to dive and resurface multiple times at the same location, a behaviour known as “milling”, which is often associated with feeding. With its particular oceanographic conditions, this sector is teeming with prey! We attempt to perform a biopsy on one of the individuals, but unfortunately we miss our mark!
