Emperor Penguin

Near Threatened

Aptenodytes forsteri

Standing over 4 feet tall and braving temperatures of -60°C, these remarkable Antarctic giants march up to 75 miles across sea ice to reach their breeding colonies.

Visual Identification

Appearance

Emperor Penguins are the largest of all penguin species, with a distinctive black and white plumage. They have a black head with white ear patches, a black back, and a white belly. Their flippers are black on the outer side and white underneath.

Both males and females look similar, with bright yellow-orange patches on the sides of their necks. Juveniles have lighter, greyer plumage and lack the vibrant neck patches of adults.

Distribution

Emperor Penguins are found exclusively in Antarctica, inhabiting the pack ice and coastal regions around the continent. They breed on stable sea ice during the harsh Antarctic winter, requiring ice that remains intact for several months.

During the non-breeding season, they spend much of their time at sea, venturing into the Southern Ocean to feed. Their distribution is closely tied to the extent and quality of sea ice.

Diet

Emperor Penguins primarily feed on fish, particularly Antarctic silverfish, as well as squid and krill. They are adapted for deep diving, allowing them to forage at great depths.

During the breeding season, they may fast for extended periods, relying on stored body fat for energy.

Behaviour

Emperor Penguins are known for their remarkable endurance, surviving harsh Antarctic winters. They huddle together in large groups to conserve heat, rotating positions to ensure all members benefit from the warmth.

These penguins are excellent swimmers, capable of diving to depths of over 500 meters in search of food.

Vocalisation

Emperor Penguins use a variety of vocalisations for communication. Their most distinctive call is a trumpet-like sound, often described as a loud 'oorr-oorr-oorr'. This call is used for individual recognition between mates and between parents and chicks in the crowded colony.

Nesting & Breeding

Emperor Penguins breed during the Antarctic winter, with pair formation occurring in March or April. They are monogamous for the breeding season but often choose new partners each year.

No nest is built; instead, the male incubates a single egg on his feet, covered by a feathered flap of skin called a brood pouch. The egg is laid in May or June and is about 12 cm long.

Incubation lasts about 65 days, during which the male fasts. After hatching, both parents take turns caring for the chick, which fledges after about 150 days.

years

The Emperor Penguin typically lives for 15 to 20 years, with a maximum recorded lifespan of 40 years.

Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.

Conservation and Status

Global Conservation Status

Near Threatened [2]

Emperor Penguins face significant threats from climate change, which affects sea ice extent and stability. This impacts their breeding habitats and food availability.

Conservation efforts focus on protecting their breeding grounds and advocating for global climate action to preserve their icy habitat.

Birdwatching Tips

  • Visit Antarctica during the austral summer (November to February) for the best viewing opportunities
  • Look for large colonies on the sea ice near the Antarctic coast
  • Observe from a distance to avoid disturbing breeding pairs and chicks
  • Use binoculars or a spotting scope for detailed views without approaching too closely
