動物図鑑

We will explain the characteristics, ecology, and habitat of macaroni penguins. This penguin lives near Antarctica and is a fashionable penguin with blonde hair growing on its head. Large colonies are formed in their habitat, indicating that they are very social.

Basic information about Macaroni Penguin

Macaroni penguins are birds belonging to the Macaroni penguin genus. Their scientific name is Eudyptes chrysolophus. They are 60-70cm long and live near the Antarctic continent. They have crested feathers and live in a very limited habitat, making them a rare species. Unlike king penguins, Adelie penguins, and gentoo penguins, they are small penguins.

What are the roots and origins of the macaroni penguin?

The roots and origins of the macaroni penguin lie in the evolutionary lineage of the “crest penguins (Eudyptes genus)” among penguins that branched off from the Antarctic region.

Outline of Origin

Macaroni penguins:

A species of crest penguin lineage that branched off from ancient penguin ancestors around Antarctica and spread to the sub-Antarctic islands.

① Antarctic Origin Antarctic Penguin

Millions of years ago, widely distributed around Antarctica.

Population fragmented due to glacial periods and ocean current changes.

② Dispersion to the Sub-Antarctic

Migrated northward due to warming and ocean current changes.

Spread to islands in the South Atlantic, Indian Ocean, and South Pacific.

③ Establishment of the Crest Penguin Genus

Evolved in isolation on each island.

A group with yellow crest feathers (Eudyptes genus) was formed.

④ Establishment of the Macaroni Penguin

A type that successfully achieved particularly wide distribution.

Colonies formed in various locations in the South Atlantic, Indian Ocean, and sub-Antarctic.

Why were they able to spread so widely?

Macaroni penguins are unique among crested penguins:

They have relatively high ocean migration capabilities.

They can widely utilize food resources (krill).

They are somewhat less dependent on islands.

Therefore, they became a widespread species rather than a species limited to certain islands.

What will happen to the classification?

Macaroni penguins were observed in the Falkland Islands in 1837 by German naturalist Johann Friedrich von Brandt. The genus name is derived from the ancient Greek eu “good” and dyptes “diver”. “Macaroni” is an 18th century British word that refers to “date man.”

Tenacious and loyal: They are loyal to their mates and breeding grounds, and tenaciously raise their young during the breeding season.

  1. Appearance

Their trademark yellow crest of feathers on their heads is flashy and unique.

They are agile swimmers in the ocean and have an adorable way of walking on land.

They can also be described as “little gentlemen with yellow crests.”

What will your personality look like?

Macaroni penguins are adapted to living in groups by forming colonies and are considered to be highly social animals. This shows that they are highly cooperative creatures.

Macaroni Penguin Personality (Behavioral Characteristics)

Social and cooperative

During the breeding season, they form large colonies and live together in groups.

Pairs work together to care for eggs and chicks.

Curious

Sensitive to their surroundings and sometimes show interest in humans and other animals.

They are bold when chasing prey while foraging at sea.

Bold and tenacious

They breed in harsh environments such as rocky areas and sandy beaches.

They are tenacious in protecting their chicks and eggs.

Loyal

Strongly loyal to their mates and breeding sites.

They often return to the same breeding sites year after year and breed with the same pair.

What is the ecology of macaroni penguins?

According to information, macaroni penguins usually use their beaks to hunt for krill and squid, and mainly eat fish and crustaceans. The breeding season is from April to May. They lay about two eggs, which are incubated for about 30-40 days and kept warm by the parents in the nest until they hatch. The chicks form crayfish and then leave the nest. The average lifespan of macaroni penguins has been recorded as about 15 to 20 years.

  1. Habitat and Environment

Distributed throughout the Antarctic and sub-Antarctic islands

During the breeding season, they form colonies on rocky or sandy coasts.

They forage in the ocean and rarely venture on land except during winter and breeding seasons.

They prefer isolated environments with little human interference.

  1. Diet (Prey)

They primarily feed on fish, krill, and small squid.

They dive underwater to pursue prey.

They primarily forage in the ocean and rarely feed on land.

  1. Breeding and Rearing

The breeding season is during the Southern Hemisphere summer (November to February).

They form large colonies on rocky or sandy coasts.

Each pair takes turns incubating eggs.

Chicks grow while being fed by their parents, and once they have fully developed feathers, they become independent in the sea.

  1. Behavior

Highly social, living in groups

Living in groups to protect themselves from predators (such as seals and seagulls)

Swimming quickly in the sea, they pursue prey

On land, they roam rocky areas and sandy beaches, focusing on breeding and protecting their chicks

  1. Adaptability

Feathers and blubber allow them to withstand the harsh low temperatures of Antarctic and sub-Antarctic waters

Streamlined body shapes suitable for diving

Sociality allows for cooperative breeding success

What are the natural enemies of macaroni penguins?

The natural enemies of the macaroni penguin are birds such as the great skuas, snow-billed plovers, southern black-backed gulls, and giant petrels. There are many enemies from the sky.

Macaroni Penguin Molting

Macaroni penguin molting is a typical “short-term, intensive, complete molt, fasting” process among crest penguins, and is a very energy-intensive process.

⏱️ Timing

Mainly after breeding season (around February-April)

Late summer to autumn in the Southern Hemisphere

Mechanism

Complete molt (total molt)

All feathers are replaced at once

Not a partial molt

Cannot enter the sea because the feathers are not waterproof

⚠️ Condition during molting

During molting:

Cannot enter the sea (no waterproofing)

Cannot forage for food

Spends time resting on land

Consumes fat to endure

In other words, “fasting + waiting life”

Macaroni Penguin Diving

Macaroni penguins are a high-performance type of crest penguin, capable of diving to medium to slightly deep and for extended periods.

Basic Data

Average Diving Depth: Approximately 20-80m

Maximum Diving Depth: Approximately 100-150m

Dive Time: 1-3 minutes (up to 4 minutes)

Relatively “Frequent Diving” Type Among Crest Penguins

① Adaptable to Mid-to-Slightly Deep Waters

Widely covers the “food-rich layer” of 20-80m depth

Can handle deeper layers than other crest penguins

② High-Frequency Diving Type

Dive → Ascend → Breathe → Immediately Dive Again

Continuous hunting with short intervals

③ Strong Adaptation to the Open Ocean

Forages while moving across wide ocean areas

A “mobile hunter” that dives while searching for food.

Macaroni Penguin Calls

Macaroni penguins have a particularly loud, metallic, and continuous quacking sound compared to other crested penguins, creating a very intense noise throughout the colony.

① Male Display Call (Typical)

A loud, continuous “quack, quack, quack” sound.

A rough, vibrating tone.

Often uttered with chest out and head shaken.

A central call for territorial assertion and courtship.

② Pair Calls

Shorter, faster-paced “quack, quack” sounds.

A call to find a mate.

Individual identification is done through vocal “patterns.”

③ Colony-Wide Sound

Thousands to tens of thousands of penguins call simultaneously.

Creates a “flood of quacking.”

Strongly resonates on rocky areas and coastlines.

An environment where presence is recognized more by sound than sight.

Seasonal Activities of Macaroni Penguins

Macaroni penguins, among crested penguins, have a typical seasonal cycle with clearly defined periods of breeding, molting, and marine life.

Spring to Summer (Breeding Season: October to February)

The most energy-consuming period of the year

Around October: Return to breeding grounds (island colonies)

Males secure territory and call out intensely to attract mates

Pair formation through courtship displays

Egg laying (usually 2 eggs)

However, the second chick often has difficulty surviving (sibling competition)

Incubation for approximately 30-40 days

After the chicks hatch, parents take turns feeding them

Key Points:

Extremely high-density colonies (tens of thousands to hundreds of thousands of birds)

Very intense calls and fighting

❄️ Autumn (Molting Season: February to April)

Complete cessation phase

Mass migration after breeding ends

Approximately 2-3 weeks of complete molting

Unable to enter the sea until feathers are replaced

Unable to forage and fasting

Key Points:

“Period of immobility”

Endures by consuming body fat

Winter (Marine Life: May-September)

Recovery and Foraging Period

Leaves the colony and migrates to the open ocean

Preys on krill, small fish, and squid

Forages while moving across wide ocean areas

Also undertakes long-distance migrations

Points:

Almost entirely at sea

Phase of energy recovery and growth

About Macaroni Penguin Chicks

Here’s a detailed summary of macaroni penguin (Eudyptes chrysolophus) chicks.

  1. Hatching

Lays one or two eggs.

Incubation takes approximately 32-34 days.

Parents take turns incubating the eggs and protecting the chicks.

  1. Appearance and Physical Characteristics

Immediately after hatching, they are covered in gray to pale down.

Their feathers are not yet waterproof, and they cannot swim.

They have a small, round body, and their limbs are underdeveloped.

  1. Growth and Development

Early Stage (1-2 weeks after hatching): They are warmed and protected by their parents.

Middle Stage (2-4 weeks): They are fed by their parents and gain strength.

Late Stage (4-7 weeks): Their feathers are replaced and become waterproof.

Chicks may form groups called “kreich” (chickling groups).

  1. Diet

Parents feed their young with fish and krill they have caught, feeding them by mouth.

After the eggs hatch, the parents take turns foraging for food.

  1. Independence

Once their feathers have grown in and become waterproof, they begin foraging at sea.

They leave the sea and become independent at about 2-3 months of age.

They live cooperatively in flocks until they reach adulthood.

Is the macaroni penguin an endangered species?

The estimated population of macaroni penguins is 18 million. From the 1970s to the 1990s, the population on South Georgia Island decreased by 50%, and the species was confirmed to have disappeared from Recalada Island in southern Chile, so it was designated as an endangered species. There are other causes as well, such as:

Competition with fishing industry

Human populations are also increasing, and we are now catching more fish through fishing. This makes it difficult for macaroni penguins to secure food. Furthermore, due to global warming, it is no longer possible to catch fish that used to be nearby.

Effects of marine pollution

There is also the impact of marine pollution. Chemicals are flowing into the ocean from oil tankers, causing further pollution. It is also believed that female penguins’ reproductive ability is declining.

Is it possible to keep macaroni penguins?

Macaroni penguins are listed as an endangered species. Furthermore, since the animals live near Antarctica, equipment that can reproduce that environment at room temperature is required, which can be quite a hurdle.

  1. Constraints as a Wild Species

A wild species adapted to the Antarctic and sub-Antarctic marine environment.

Because they are adapted to the harsh low temperatures and extensive foraging areas, captivity in an artificial environment is extremely difficult.

Few zoos around the world exhibit macaroni penguins, and they cannot be kept at home.

  1. Difficulties in Breeding

Temperature Control: Near-freezing temperatures are required.

Aquarium Size: A large saltwater pool is required for swimming.

Dietary Management: A large and stable supply of fish and krill is required.

Health Management: Wild species are susceptible to stress and disease, making it difficult for them to survive in an artificial environment.

Legal Restrictions: The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) imposes strict restrictions on import, export, and breeding.

  1. Summary

Macaroni penguins are virtually impossible to breed at home or in small facilities.

They can only be kept in specially controlled environments at specialized facilities or research institutes.

There are few examples of them in captivity, and conservation and observation must be carried out in the wild.

Zoos where they are kept (Japan and around the world)

The Macaroni penguin is a relatively common species of crested penguin found in many zoos and aquariums, and is considered “commonly seen” in both Japan and around the world.

Japanese Breeding Facilities

In Japan, they are mainly kept in aquariums:

Kamogawa Sea World (Chiba)

Nagoya Port Aquarium (Aichi)

Kaiyukan (Osaka)

Adventure World (Wakayama)

Sunshine Aquarium (Tokyo)

A staple crest penguin exhibit in Japan

World Breeding Facilities

Macaroni penguins are widely kept worldwide:

United States (New York, San Diego, Pittsburgh, etc.)

Canada (Montreal, etc.)

United Kingdom (London Aquarium, etc.)

Belgium (Antwerp Zoo, etc.)
