Macaroni Penguin

Among the six species of penguins that belong to the group including the Rockhopper Penguin and the Royal Penguin, the Macaroni Penguin is the most iconic representative! Notably, all members of the Macaroni Penguin genus feature distinctive crest feathers. But if you observe closely, each has its unique way of sporting these feathers. Let's explore the appearance and personality of the Macaroni Penguin!

Macaroni Penguin Basic Infomation

Order: Sphenisciformes, Family: Spheniscidae, Genus: Eudyptes

Height: Approximately 71 cm

Weight: Males: 5.2 kg during breeding, Females: 5.3 kg during breeding; Males: 3.3 kg after egg laying, Females: 3.9 kg after egg laying

Beak Length: Males: 6.1 cm, Females: 5.3 cm

Macaroni Penguins are distinguished by black cheeks and throats, white underbellies, and black feathers covering their backs, with pink feet and black soles. Their heads are adorned with beautiful yellow and orange crest feathers, and their beaks are a deep brownish-orange. Males and females look identical, making them difficult to differentiate, though males are generally larger.

Royal Penguins resemble Macaroni Penguins but have white faces, making them easier to distinguish.

Macaroni Penguins breed on various sub-Antarctic islands, forming large colonies called 'rookeries' on coastal rock slopes and sometimes in tussock grass. They use small stones and rock fragments to build their nests.

Females typically lay two eggs in November, though occasionally three. Initially, the male incubates the eggs for about 10 days, followed by the female for 12-14 days, and then the male again for about 10 days.

From hatching to independence, chicks are initially brooded by their parents and then placed in crèches (nursery groups). Parents continue feeding them until they fledge at about 60-70 days old, gradually replacing their fluffy down with adult feathers, including the distinctive crest.

Macaroni Penguin Q&A

What is the origin of the Macaroni Penguin's name?

In the 18th century, English men with fashionable and flamboyant hairstyles were called 'macaronis'. Similarly, the term 'macaroni' in English implies a 'foppish' man. The name 'Macaroni Penguin' comes from the bird's striking yellow and orange crest feathers, reminiscent of the extravagant hairstyles. The scientific name, 'Eudyptes chrysolophus', includes 'chrysolophus' which means 'golden crest', further emphasizing their ornate appearance.

Why does the Macaroni Penguin live there?

Macaroni Penguins breed on various sub-Antarctic islands such as South Georgia, Crozet, Kerguelen, Heard, and McDonald Islands, as well as Marion Island. Sightings have also been reported along the coasts of South Africa, Australia, and New Zealand. While some of these instances might be due to stranding, it's believed that Macaroni Penguins favor sub-Antarctic islands due to the abundant presence of their prey, such as krill, around these islands.

What does the Macaroni Penguin eat?

The Macaroni Penguin primarily feeds on krill by diving into the sea, though their diet can also include squid, octopus, and small fish, especially during the breeding season. Chicks are fed regurgitated squid and octopus by their parents.

Is it true that only one chick is raised by Macaroni Penguins?

Yes, it is true. Typically, the first egg laid is smaller and often not incubated or accidentally broken by the parents. Although two eggs are laid, usually only one chick is successfully raised. This is a survival strategy in the harsh natural environment, ensuring that at least one strong chick survives.

Were Macaroni Penguins also victims of penguin oil exploitation?

Yes, like the Royal Penguins, Macaroni Penguins were also exploited for oil extraction. Although specific records about Macaroni Penguins are scarce, it's known that other species like the King, Gentoo, and Rockhopper Penguins were also heavily hunted for their oil.

I want to know more about the personality of Macaroni Penguins!

While specific details are limited, Macaroni Penguins are thought to be quite aggressive, a trait possibly linked to their living conditions. They form very large colonies with nests closely packed together, which often leads to territorial disputes and aggression as they protect their nests and chicks.

Where can I see Macaroni Penguins?

In Japan, Macaroni Penguins can be viewed at several locations including the Sendai Uminomori Aquarium, Hakkeijima Sea Paradise, Hakone-en Aquarium, Kaikyokan Aquarium, and Nagasaki Penguin Aquarium. For those interested in seeing them in the wild, joining an Antarctic cruise might be an option, though it can be quite expensive.

Does the Macaroni Penguin have any natural predators?

The primary natural predators of Macaroni Penguins include large seabirds like the Skua and the Giant Petrel. However, humans have been the most significant threat, impacting their populations through oil exploitation and habitat disturbances. Climate change, leading to a reduction in their prey due to warming oceans, also poses a significant threat to their populations.

What is the lifespan of a Macaroni Penguin?

Macaroni Penguins can live for over 20 years in the wild, although their lifespan can vary depending on environmental conditions and predation pressures.
