Little penguin: where and when to see them

Little penguins are the smallest living penguins, with blue-toned upperparts and white underparts. The catalog name covers birds in Australia and New Zealand whose treatment differs among taxonomies: Australian little penguin and New Zealand little penguin are often recognized separately. They spend much of their lives at sea but depend on coastal nesting shelters. Shore-based viewing usually focuses on their quiet return to colonies after sunset, under carefully managed conditions.

Adults commonly leave colonies before dawn and return after dark, reducing exposure to predators on land. They nest in burrows, rock cavities or other sheltered spaces, sometimes beneath buildings. Pairs communicate with surprisingly loud calls and may reuse successful nest sites. Breeding schedules vary with locality and food supply. During the annual moult, birds remain ashore while replacing their plumage, relying on stored energy because they cannot feed normally at sea. Little penguins are highly social birds, often foraging in groups and returning to colonies in larger rafts before coming ashore. During the moult, which lasts for about two to three weeks, they appear ruffled and spend almost all their time ashore in a sheltered spot.

• Little penguins are the smallest penguins alive today.
• Their blue colour comes from the microscopic structure of their feathers.
• Adults replace their entire plumage during a concentrated annual moult.
• Some colonies occupy coastal suburbs, making traffic and dog management important conservation measures.

Choose a locally managed colony program rather than assuming one breeding calendar applies everywhere. Many Australian and New Zealand colonies have busy breeding periods between spring and summer, but attendance varies. Evening viewing arrangements, closures and moult timing should be checked locally. In southern Australia and New Zealand, the peak breeding season often extends from September to March, during which activity around colonies is highest. Some colonies, particularly in northern New Zealand, may show more protracted or even year-round breeding activity.

These penguins use temperate coastal waters adjoining islands, sheltered bays and mainland shores. Nesting habitat includes sandy burrows, vegetated slopes, boulder cavities and suitable artificial shelters. Colonies need unobstructed access between the sea and protected resting or breeding sites. They are often found in coastal areas close to human habitation, utilizing structures like rock walls, jetties, and even under houses for shelter. The specific microhabitat within a colony can vary, from open sand to dense vegetation, influencing burrow depth and protection from weather.

Their diet consists mainly of small schooling fish, with squid and crustaceans contributing according to local availability. Prey is captured at sea. Changes in nearby fish stocks and marine conditions can affect adult condition, breeding success and the distance travelled to feed. Foraging typically occurs within a few kilometers of the colony, but individuals may travel much further, up to 25 kilometers, in search of food. Their specialized eyesight helps them locate prey in low light conditions underwater.

Identification

Little penguins are distinguished from larger regional penguins by their tiny size and blue-grey upperparts, but separating Australian and New Zealand forms visually is unreliable. Their scientific name, Eudyptula minor, means 'little good diver', reflecting their small size. Juveniles have slightly duller plumage and a shorter bill compared to adults.
