Scientists determine geese died due to exhaustion and salt-poisoning. More birds end up dying because of the long flights they undertake, in extreme conditions.
It's not the first time snow geese have died in large numbers in western Nunavut. The cause of this event is under investigation, but overpopulation could have played a role, says the Canadian Wildlife Service.
Natural causes led to the death of more than 1,000 geese on Long Point beach outside Cambridge Bay this past August, a pathologist’s report has found.
