5 Facts About Erect-crested Penguins

  1. Their populations have been in decline since the 1970s, although scientists have not been able to pinpoint with certainty what the cause of their decline is. But they do face threats from global warming, commercial fishing bycatch, invasive predators, oil spills and disease.

  2. Erect-crested Penguins get their name from the stiff yellow feathers above their eyes.

  3. When courting a mate these birds have been observed swinging their head up and down whilst making a trumpeting-like sound. They breed in October and will lay 2 eggs, with the smaller egg usually being left whilst the larger egg is incubated for at least 35 days.

  4. They have spikes on their tongues and at the back of their mouth which help to hold their prey and swallow them all in one go! They typically eat fish, krill and squid.

  5. Males have been seen fighting with their bills and flippers at nesting sites in competition for mates and nesting spots.

5 Facts About Yellow-eyed Penguins

  1. The yellow-eyed penguin is now the only member of the genus Megadypte, there use to be a second member of this genus, the Megadyptes waitaha, another species of penguin to live in New Zealand however it went extinct hundreds of years ago and tragically the yellow-eyed penguin appears to be on the same track.

  2. Juvenile yellow-eyed penguins will moult in February and it will take around 2/ 3 weeks for them to fully shed their feather. During this time they are unable to go in the water because their plumage is not well insulated and it is not waterproof. This is when they are at their most vulnerable.

  3. These penguins have one of the longest breeding seasons, from August to March. Their nests are made from solid structures such as rocks and trees and unlike other penguin species they do not breed in colonies. Most breeding pairs are monogamous. 

  4. You can actually find the yellow-eyed penguin on the New Zealand $5 bill.

  5. The biggest risks to the yellow-eyed penguins is entanglement in fishing gear, diseases such as avian malaria and blood parasites as well as invasive mammal species.
