The hope, as GREMM president told Le Devoir, was that one of the other females might be induced to feed her. Sadly, most recent reports suggest it has not yet happened - which makes the situation particularly precarious for the baby beluga.
Beluga whales nurse their young for around two years. This baby, just days old, is desperately in need of a lactating mother to give her a vital start in life.
"For now, we do not yet know the outcome of the story," Michaud told Le Devoir.
The calf's survival is particularly vital, as the beluga whale population ebbs to unprecedented levels in the St. Lawrence region.
The area, Michaud notes, once boasted thousands of beluga whales. Today, the population is estimated at less than 900. Much of that decimation, according to the World Wildlife Fund of Canada, is due to the river's rising pollution levels.
But this baby beluga, at least, has a fighting chance. She held out on the beach for her young heroes.
