Her field marks
It is easier to identify Marjo from her left side thanks to the scar on her peduncle resembling a pair of eyeglasses. To confirm her identity from the right, one must carefully study the details of her dorsal crest.
Our first encounter with Marjo goes back to 1994, at which time she was gray. She turned entirely white around 2000. Belugas fade from gray to white in colour between the ages of 12 and 16. Marjo would therefore have been born in the mid-1980s, around the same time our beluga research project was initiated.
Her small size, habits and regular presence in herds comprising adults and young suggested that Marjo was a female belonging to the Saguenay community. In their summer range, females form large communities in which they tend to newborns and young. These communities are faithful to traditional territories and exchanges between them are uncommon. The presence of a newborn at Marjo’s sides in 2014 confirmed her sex.
In 2001 and 2002, she had also been seen with a young gray individual, possibly a calf that she had borne the year before. At birth, calves have brown skin. Later, they turn bluish gray and remain this colour until they’re about two years old. Juveniles aged 2 and up have gray skin, which then fades to white when they reach adulthood.
How Marjo’s story unfolds will help us better understand the social and reproductive lives of St. Lawrence belugas. By better understanding how belugas live, we will better be able to protect them.
