Blue whales are doing better than I realized.
So far, 41 blue whales in South Georgia have been photo-identified between 2011 and 2020. None of the South Georgia whales matched the profiles of the 517 whales in the Antarctic blue whale photographic catalogue.
“We don’t quite know why it has taken the blue whales so long to come back,” Calderan said. “It may be that so many of them were killed at South Georgia that there was a loss of cultural memory in the population that the area was a foraging ground, and that it is only now being rediscovered.”
Still fewer than 600 catalogued individuals, but it’s certainly good to see this species slowly increasing in numbers and reappearing in historical regions.
