His field marks
DL9039 has a gray spot on his right flank.
A recent addition to our family album, DL9039 has only been known by the GREMM since 2011. We subsequently spotted him in 2013 and 2015. The first time we observed him, we noted him as being a young gray. When he was encountered in 2013 and 2015, his skin was still gray, but quite pale. Belugas fade from gray to white in colour between the ages of 12 and 16. DL9039 would therefore have been born in the early 2000s.
At the present time, we are unable to identify which male network DL9039 belongs to or who his faithful companions are. Indeed, there exists a sort of sexual segregation in belugas. Bulls and cows live separately and frequent different sectors, particularly in summer. Three male networks are known, two of which ply the waters of the Saguenay Fjord and the head of the Laurentian Channel while the third one, nicknamed the “Downstream Boys”, uses the head of the Laurentian Channel as well as the downriver portion of the Estuary. Even if their territories overlap, individuals from one network seldom come into contact with males of other networks.
When they reach adulthood, males tend to form stable groups of companions. These associations, which are established gradually in adulthood, may play an important role in belugas’ reproductive lives.
How DL9039’s story unfolds will teach us volumes on the evolution of belugas’ social lives. For example, which sector will he favour as he grows older? Who will his lifelong companions be? By better understanding how belugas live, we will be able to better protect them.
