July 28, 2004: we observe Écho off of Île Blanche, in the Rivière-du-Loup sector. He is swimming in a herd of 40 belugas. Within the herd, we notice a few entirely white individuals, though 70% of them are gray or slightly gray. The herd is composed mostly of young belugas, grays and others that we refer to as “dirty white”, which are less than 20 years old. The animals are active and are milling, which consists of swimming in circles and diving and resurfacing multiple times at the same spot. This behaviour is often associated with feeding. We attempt to place a VHF radio tag on one of the individuals, but we miss our target! Toward the end of our encounter, the animals begin to head upstream.
