Physical Description

The Yellow-eyed Penguin, or Megadyptes antipodes, is a medium-sized penguin measuring between 22 to 31 inches in length and weighing from eight to approximately 19.6 pounds. What sets this species apart from other penguins is its pale yellow eyes and a bright yellow band that extends from the eye to the back of its head. Its body is predominantly slate grey, with white underparts.

Characteristics and Behavior

This penguin species is mostly silent, making a unique bray-like call at nest and breeding sites. The Yellow-eyed Penguin is known to be long-lived, with some reaching up to 20 years of age. Interestingly, males are generally longer-lived than females, creating a sex ratio of 2:1 around the age of 10-12 years.

Feeding Habits


Feeding predominantly on fish, the diet of the Yellow-eyed Penguin includes species like red cod, opal fish, sprat, and squid. They also consume some crustaceans, including krill. Recently, it was discovered that they even feed on jellyfish, mainly targeting the juvenile fish and fish larvae associated with them.

Breeding and Life Cycle

Yellow-eyed Penguins breed from August through March, laying eggs in shallow scrapes made of leaves, grass, and twigs. The eggs are incubated for 39 to 51 days, with both parents sharing the incubation duties. After the chicks hatch, one parent remains with them while the other goes out to sea to forage for food. By the time they are six weeks old, both parents go out to the sea, leaving the chicks alone during the day. The chicks usually fledge or develop feathers sufficient for flight, by mid-February and are completely independent from then on.

Habitat and Distribution


Yellow-eyed Penguins are endemic to New Zealand, living on the southeast coast of the South Island, Foveaux Strait, and Stewart, Auckland, and Campbell islands. Historically, their breeding habitat was primarily in coastal forests and mixed-species scrub on slopes above landing areas. However, due to habitat destruction, they are now found in scrub remnants. When it comes to foraging, they do so over the continental shelf.

Migration Patterns

While adult Yellow-eyed Penguins are sedentary, the juveniles disperse to the north as far as the Cook Strait. This migration pattern is unique among penguin species and adds another layer to the intriguing life of these birds.

Endangered Status

The Yellow-eyed Penguin is listed as an endangered species on the IUCN Red List. Its population has seen a significant decline in recent decades, with fewer than 2,000 breeding pairs remaining.

Threats and Conservation

This unique penguin species faces several threats, including food shortages due to sea-temperature changes driven by global warming. Other threats include loss of natural breeding habitat, predation by introduced mammals, and entanglement in fishing nets. Conservation efforts are underway to protect and increase the population of these birds.

Role in Culture and Tourism

The Yellow-eyed Penguin holds a special place in New Zealand culture and tourism. It appears on the reverse side of the New Zealand five-dollar note, symbolizing the country's commitment to wildlife conservation. These penguins also attract tourists to New Zealand, with several mainland habitats providing viewing hides for observing these unique creatures.

Interesting Facts

Here are some intriguing facts about the Yellow-eyed Penguin:

  • It's one of the rarest penguin species in the world.
  • Unlike other penguin species, Yellow-eyed Penguins are mostly silent.
  • Males are generally longer-lived than females.
  • They have a distinct yellow band that extends from the eye to the back of the head.


    The Yellow-eyed Penguin, or Megadyptes antipodes, is more than just another member of the penguin family. With its unique physical characteristics, intriguing behavior, and the challenges it faces for survival, it represents a critical piece of New Zealand's rich biodiversity. As we continue to learn more about this fascinating species, it's crucial that we also work towards its conservation and ensure that future generations also get to witness the beauty of this unique bird
