  • Known since : 1990

Her field marks

The dorsal crest of DL0584 has too few markings to identify her. She is recognizable only from her left side thanks to the deep, irregular scar below her dorsal crest, which has become her signature.

Life history

When we first encountered her in 1990, DL0584 was still gray. She gradually faded to become all white in the late 2000s. Her dorsal crest remained black, however, making her easy to identify. Belugas fade from gray to white in colour between the ages of 12 and 16. DL0584 would therefore have been born in the mid-1980s.

DL0584 is a female. In summer, 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.

DL0584 is regularly observed in the company of Slash and Élizabeth, both members of the Saguenay community. Associations between females of the same community are generally not very stable. They may vary depending on the females’ reproductive status and whether or not they are pregnant or accompanied by a calf.

Over the years, DL0584 has been seen regularly in groups comprising newborns. Once she was seen with a one- or two-year-old individual that seemed to be her own. Mother-calf relationships are difficult to establish with certainty, however. Eventually, once we’ve performed a biopsy, DL0584’s DNA will reveal the details of her family tree.

How DL0584’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.

    We’re at the mouth of the Saguenay, heading toward Île Rouge. DL0584 is swimming in a herd of approximately sixty individuals comprising both adults and young, including two newborns. We observe two large concentrations of animals: nearest to us is a group consisting of females and young, followed by a group of adult bulls. DL0584 is in the company of a known female, Miss Frontenac, and the second-year calf of the latter.

    The mouth of the Saguenay is a meeting place! Here, networks of male belugas regularly cross paths with those comprising females and young. Short-lived herds form here due to the abundance of food. Moreover, amongst the beluga herd we spot a number of seals, birds, and minke whales. That’s what we call well-stocked waters!

  • The naturalists of the GREMM

    The naturalists of the GREMM adopted DL0584 (pending).

    $4,624 raised of $5,000.00 total.

    Être naturaliste au Groupe de recherche et d’éducation sur les mammifères marin (GREMM), c’est pas juste notre travail, c’est une vocation, voire une passion.

    On accueille le public, on leur parle de baleines, on leur raconte des histoires… on leur fait vivre une expérience unique. On leur apprend tout ce qu’on sait au sujet du mystérieux monde des mammifères marins et, particulièrement, de ceux qui arpentent le Saint-Laurent. Nous sommes d’ailleurs plusieurs groupes d’interprètes et de naturalistes à œuvrer pour divers organismes le long du fleuve. Nous partageons tous cette même passion.

    L’éducation scientifique n’existe pas sans la recherche. Et on protège ce que l’on connaît. On le répète souvent : la santé des bélugas, c’est le reflet de la santé du Saint-Laurent. C’est la santé et l’équilibre d’un écosystème fragile qui touche les bélugas mais bien plus. Le fleuve est source de vie, pour nous et pour tout ce qui nous entoure.

    Cela fait un moment que nous l’attendions : le retour du projet “Adoptez un béluga” pour soutenir la recherche sur ces majestueuses baleines blanches. Alors tous les naturalistes, les présents, les anciens, les collègues, lançons-nous dans une adoption collective pour, nous aussi, faire notre part! Et pas n’importe quelle adoption! Nous avons choisi DL0584, un béluga qui fréquente régulièrement l’embouchure du Saguenay. Vous pourrez ainsi avoir la chance de l’observer depuis le Centre d’interprétation des mammifères marins (CIMM) à Tadoussac et depuis le Site d’interprétation et d’observation de Pointe-Noire, de l’autre côté du fjord.

    Lorsque nous aurons récolté les fonds nécessaires pour l’adoption de notre béluga, nous le nommerons tous ensemble. Parce que nous avons besoin de plus de connaissances pour continuer de les protéger, adoptons un béluga!
