Magellanic penguins rescued off the coast of Rio de Janeiro state receive treatment from a veterinary student at the Rio de Janeiro Zoo, Rio de Janeiro, Brazil, August 15, 2000. The magellanic penguins get to the Argentinian and Uruguayan coast during their migration from the Patagonia to Brazil in July. While large numbers of penguins arrive on Rio de Janeiro's beaches every year, swept to sea by strong ocean currents from the Strait of Magellan, this year is seeing higher numbers and more dead penguins than usual.
