His field marks

We’re not yet able to identify Bilou from the right side. His left flank shows several scars, the main one of which being nearly twice as long as his dorsal crest.

Life history

It was in 1997 that we encountered Bilou for the very first time. He was pale gray at the time. Beginning in 2003, he was always noted as being “white”. Belugas fade from gray to white in colour between the ages of 12 and 16. Bilou would therefore have been born around 1990. His sex was confirmed by genetic analysis of a biopsy taken in 1998: Bilou is a male.

Bilou has been regularly observed in large, highly dynamic herds composed essentially of young males. Like adult males, young males stay away from herds of females accompanied by young in the summer. In contrast with adult males, young males do not seem to form lasting associations with other males.

These associations are established a little later in their lives. They may play an important role in belugas’ reproductive lives. To date Bilou has no known faithful companion.

How Bilou’s story unfolds will teach us volumes on the evolution of belugas’ social lives. By better understanding how belugas live, we will better be able to protect them.

  • JULY 23, 2013

    July 23, 2013: we’re with Bilou off the coast of Île aux Pommes near the south shore. He’s in one of the seven groups of young grayish belugas that are stirring at the water’s surface. Their tails and heads can be seen protruding from the water. A calf passes from one group to another without appearing to us to be accompanied by any one adult in particular. When we leave the sector more than 70 belugas are present.
