Did You Know? Incredible Rockhopper Penguin Facts

One of the best rockhopper penguin facts is that they are the smallest species of crested penguins.

The rockhopper penguin (Eudyptes chrysocome) is a rare penguin species. They are very rare species to be  found and they are the smallest species of crested penguins in the world. They also come into the category of the most aggressive penguins in the world! There are three species of rockhopper penguin in the world. They are the northern rockhopper penguin (Eudyptes moseleyi), the southern rockhopper penguin (Eudyptes chrysocome), and the eastern rockhopper penguin (Eudyptes chrysocome filholi).

A rockhopper penguin has bright red eyes and a long black and yellow feather-like crest, making them unique from other penguins. Scientists researched these bright red eyes and concluded that their bright red eyes are most probably part of the social signaling that takes place among the birds.

The breeding season and cycle of a rockhopper penguin is more variable than it is for other penguins. The female rockhopper penguin lays two eggs which are protected by both parents. These parents will protect their rockhopper penguin eggs from the time they are laid until the chicks are old enough to survive on their own. Predators of rockhopper penguins include sea animals and other birds like killer whales, sea lions, and fur seals.

Rockhopper penguin mating is a little unique as they usually breed with the same partner every year throughout their life. That is why they can be described as monogamous animals. Their breeding period lasts from early spring to late summer and they usually breed in their vast colonies. After the mating process is complete, a female penguin lays two eggs which both parents take turns incubating. They incubate and guard these eggs for months. The second egg is always smaller than the first and when the eggs hatch the parents take care of the chicks, feeding them and teaching them to survive alone one day

What is their conservation status?

According to the IUCN, the rockhopper penguin (Eudyptes chrysocome) is classified as Vulnerable when it comes to conservation. This means the rockhopper penguin population is decreasing year by year. Oil spills, such as a large accident in 2011, are one main reason for their population decreasing as this incident alone resulted in hundreds of thousands of rockhopper penguins becoming covered with thick oil, eventually causing them to die.

Why do rockhopper penguins lay two eggs?

Southern, eastern, and northern rockhopper penguins always lay two eggs. The second egg is known as the reassurance egg because the first year of the penguin's life is very difficult and they often sadly die. Rockhopper penguins, therefore, lay two eggs so that if one chick dies, they will still have another one.
