SAO PAULO -- Marine biologists and veterinarians say the bodies of more than 500 penguins have washed up on beaches in southern Brazil over the past week.

They tell the G1 online news site that the Center of Coastal and Marine Studies is investigating what caused the deaths of the 512 penguins found on beaches of the southern state of Rio Grande do Sul. The cause of death should be known in about 30 days.

Calls to the center on Saturday went unanswered.

Biologists at the center told G1 the penguins were migrating north from Argentina in search of food in warmer waters. They say the birds appeared well-fed, unhurt and without oil stains.
