Where does the name Chinstrap Penguin come from?

The term Chinstrap refers to the helmet strap of a hat. In other words, it was named after the black line around the chin area that resembles the strap of a hat or helmet. By the way, in Japan, it is called the Mustache Penguin because it is thought to resemble a mustache.

Why does Chinstrap Penguin live there?

Chinstrap Penguins breed and raise their young on various islands, including those in the sub-Antarctic and Antarctic Peninsula. Some of these islands include Bouvet Island, the South Sandwich Islands, South Georgia Island, the South Orkney Islands, the South Shetland Islands, Peter I Island, Scott Island, and the Balleny Islands.

They are also found from the north to the Amber Islands on the Antarctic Peninsula. In addition, they have been sighted along the coast of Antarctica, in the northern ice zone, and in Adélie Land to the southeast. Chinstrap Penguins have also been observed on Macquarie Island in Tasmania and Australia.

While it is possible that some sightings may be due to individuals being carried by currents, one theory suggests that a large population of Antarctic krill resides beneath the ice around the Antarctic Peninsula and islands. This abundance of food makes these areas ideal for Chinstrap Penguins to thrive.

What does Chinstrap Penguin eat?

Chinstrap Penguins dive into the sea and eat small fish, Antarctic krill, and crustaceans. In the case of chicks, they receive digested Antarctic krill from their parents by mouth.

Is it true that Chinstrap Penguin is said to represent Antarctica?

When you think of penguins living in Antarctica, many people might imagine the Emperor Penguin with its beautiful yellow markings on its white belly. So why is the Chinstrap Penguin considered the representative of Antarctica? The secret lies in its scientific name.

The scientific name of the Chinstrap Penguin is “Pygoscelis antarcticus,” and “antarcticus” means “of Antarctica,” and only the Chinstrap Penguin is listed. It is said to be the representative of Antarctica because it is the only species with “antarcticus” in its scientific name.

However, in reality, this secret seems to be simply because the Chinstrap Penguin was the first penguin discovered in Antarctica. Therefore, it does not seem to be called the representative of Antarctica because of any special reason.

Is it true that Chinstrap Penguin coexists with other penguins?

In conclusion, it’s true. On King George Island, one of the South Shetland Islands, not only Chinstrap Penguins but also Gentoo Penguins and Adélie Penguins, which belong to the same genus, inhabit the island.

Therefore, it is said that Chinstrap Penguins sometimes get mixed up in Adélie Penguin colonies. However, this raises a question. Don’t these three species of penguins compete for food when they live in the same place? Actually, penguins seem to be aware of this issue. They control their feeding habits by changing the location where each penguin feeds and adjusting their breeding seasons to avoid competition for food.

For example, Gentoo Penguins mainly catch fish along the coast, while Adélie Penguins and Chinstrap Penguins catch Antarctic krill further offshore.

Although Adélie Penguins and Chinstrap Penguins eat the same food, they adjust their breeding seasons so that Adélie Penguins lay eggs from October to November and Chinstrap Penguins lay eggs from November to December. This way, even if other penguins live on the same island, they can coexist peacefully.

Chinstrap Penguins are known to be the most quarrelsome and bold among the Adélie Penguins. As a result, they sometimes fight with their fellow penguins. Moreover, instead of running away when other penguins or animals enter their territory, they tend to jump at opponents larger than themselves.

Is there a place where I can see Chinstrap Penguin?

As of November 2021, there are three places in Japan where Chinstrap Penguins are bred: Nagoya Port Aquarium in Nagoya City, Aichi Prefecture, Adventure World in Shirahama Town, Wakayama Prefecture, and Nagasaki Penguin Aquarium in Nagasaki City, Nagasaki Prefecture. For those who want to see Chinstrap Penguins in the wild, joining an Antarctic cruise is an option. However, please note that the travel expenses can be quite high. You can apply through a travel agency. I hope this information is helpful!

Does Chinstrap Penguin have natural enemies?

Chinstrap Penguins have natural enemies such as Orcas and Leopard Seals that lurk in the sea. Additionally, the South Polar Skua, a bird, targets their eggs and chicks. However, humans might be the biggest threat to Chinstrap Penguins.

Currently, the International Union for Conservation of Nature (IUCN) has designated Chinstrap Penguins as “Least Concern” in terms of endangerment. However, in recent years, the average temperature on the Antarctic Peninsula has risen due to global warming, and Chinstrap Penguins are said to be affected by this.

Penguins are generally resilient to cold but sensitive to heat. Therefore, when the average temperature in November, their breeding season, rises, it can lead to a significant loss of energy.

Moreover, it is said that it rarely rains on the Antarctic Peninsula. However, there was a year when it rained continuously. As a result, cotton-like chicks without water-repellent properties became soaked and died from freezing.

As you can see, climate change has caused unexpected phenomena in various parts of the world. This is an opportunity for us to think together about building a better relationship between humans and penguins.

What is the lifespan of the Chinstrap Penguin?

The lifespan of Chinstrap Penguins, which live in a harsh natural environment, is up to 18 years at most.
