They eat squid, krill , and other small fish. Rockhoppers live on most of the islands in the Antarctic region. There are major colonies on the Falkland Islands. It is estimated that there are over 3 million breeding pairs. They get their name because they hop over rocks and crevices on the shores where they live.
Penguins make their nests by scraping a hole in the ground and lining it with dried grasses.
Two eggs are usually laid. Often only one chick is survives. The first egg is smaller and often gets eaten by predators. The second egg is larger and the chick that hatches from this egg has a better chance of surviving. Rockhoppers are loud, noisy, and feisty birds.
