Galápagos penguins are in danger of becoming extinct. The weather is the biggest problem for these penguins. Every so often, the winds that blow across the Pacific Ocean die down. This effect is called El Niño. El Niño changes the currents of the water. The cold water the penguins love to swim and feed in disappears. In El Niño years, the water around the islands can be much warmer. The change in temperature kills the plankton that fish eat. The fish move to deeper waters. And the fish-eating penguins are left without food.
