Hundreds of dead penguins dot Brazil's beaches - Yahoo! News

SAO PAULO – Hundreds of penguins that apparently starved to death are washing up on the beaches of Brazil, worrying scientists who are still investigating what's causing them to die.

Most were Magellan penguins migrating north from Argentina, Chile and the Falkland Islands in search of food in warmer waters.

Many are not finding it: Autopsies done on several birds revealed their stomachs were entirely empty — indicating they likely starved to death, Nascimento said.

Scientists are investigating whether strong currents and colder-than-normal waters have hurt populations of the species that make up the penguins' diet, or whether human activity may be playing a role.
