Update from the Orca Research Trust:
"After spending 22 hours watching the mother orca carrying her dead calf, we were devastated to see her driven off, due to bad driving from a few boaties (approaching too fast and too close). Although many people showed great respect and sympathy when they approached (and drove considerately - thank you to those folks), the few who didn’t caused the mother to abandon her baby."
