But biologist Erli Costa of Rio de Janeiro's Federal University suggested weather patterns could be involved. "I don't think the levels of pollution are high enough to affect the birds so quickly. I think instead we're seeing more young and sick penguins because of global warming, which affects ocean currents and creates more cyclones, making the seas rougher," Costa said. Costa said the vast majority of penguins turning up are baby birds that have just left the nest and are unable to out-swim the strong ocean currents they encounter while searching for food. Every year, Brazil airlifts dozens of penguins back to Antarctica or Patagonia.
