The penguins are currently migrating from Patagonia to south Brazil – a journey which no doubt claims some lives but not at this magnitude.
According to the Brazilian Center for Coastal Studies at the Federal University of Rio Grande do Sul, however, the penguins likely died of natural causes.
In a press release, the center said it had analysed the dead animals’ conditions and found that most of the birds were young, and showed no signs of external injury or oil in the plumes.
According to biologist Mauricio Tavares: “Birds in the first year of life are inexperienced,” adding that dead birds at this time of year is common and the result of “the process of natural selection”.
Some questions have been raised as to just how natural this occurrence is, however. According to TreeHugger, dead penguins washing ashore happens with “disturbing” regularity.
A more detailed report on the latest penguin deaths is expected later this month.
