Her field marks
It is much easier to identify Blanche from the left side, thanks to the large bulge in the centre of her flank. This mark has become more complex over the years. She only has a small gash in her dorsal crest.
We first encountered Blanche in 2001. As she was already all white at the time, it is difficult to determine her age. Belugas fade however from gray to white in colour between the ages of 12 and 16. Dl1757 was therefore born before 1989!
Easily recognizable thanks to an outgrowth on her left flank, Blanche has been observed nearly every summer since 2001. She failed to show up just once, in 2003.
In summer, females form large communities in which they tend to newborns and young. These communities are associated with traditional territories. Blanche belongs to the Saguenay community. The presence of newborns at Blanche’s sides in 2005, 2008 and 2014 not only confirms her sex, but also the fact that she is a very productive matriarch.
Her calf born in 2005 had a distinctive mark, a scar ressembling a Daisy upon which she was nicknammed Marguerite. Marguerite is a female. She gave birth to her first calf in 2014 at the age of 9. This is the first time we ever monitored a female from her birth to her first calf! Blanche thus became the first known “grandmother” in the St. Lawrence.
How Blanche’s story unfolds will teach us volumes on the evolution of belugas’ social and reproductive lives. By better understanding how belugas live, we will better be able to protect them.
