Macaroni Penguin: where and when to see them

The macaroni penguin is a robust crested penguin of the Southern Ocean, recognized by bright yellow-orange plumes that meet across its forehead. It breeds mainly on subantarctic islands rather than the Antarctic continent itself. Enormous colonies can occupy steep, noisy coastal slopes, but geographic abundance is uneven and several populations have declined. Its life alternates between concentrated periods ashore for breeding or moulting and extensive movements at sea in search of food.

Macaroni penguins return to dense colonies for a tightly seasonal breeding cycle. Pairs use calls and displays to recognize one another amid the crowd. Females normally lay two differently sized eggs, but the smaller first egg usually fails and only one chick is raised. Parents alternate incubation and feeding duties, with chicks later gathering in groups. After breeding, adults build reserves before remaining ashore for a complete annual moult. Courtship involves head-shaking, bowing, and mutual preening, reinforcing pair bonds. After moulting, adults spend several months exclusively at sea before returning to the colonies for the next breeding cycle.

• The name recalls the extravagant dress of eighteenth-century 'macaroni' fashion.
• The first egg is markedly smaller than the second and usually does not produce a surviving chick.
• Breeding adults recognize mates and offspring through vocal cues in crowded colonies.
• Their principal breeding strongholds lie north of the Antarctic continent on subantarctic islands.

Austral summer, broadly November through March, offers the relevant regional travel window. Nesting, chick-rearing and moulting occur at different stages within it. Most standard Antarctic Peninsula itineraries do not reach major colonies, so species-specific access depends strongly on the permitted route. Early in the season, adults arrive at breeding sites and courtship rituals begin. By late summer, fledged chicks depart for the open ocean and adults undergo their annual feather replacement.

Breeding colonies occupy rocky shores, tussock-covered slopes and exposed coastal ground on subantarctic islands and a few maritime Antarctic sites. At sea, birds use cold, productive Southern Ocean waters. Many colonies are remote, steep or otherwise inaccessible to ordinary visitors. These colonial nesters favor sheltered coves or valleys offering some protection from prevailing winds. Their breeding grounds often show significant modification from guano accumulation and trampling by generations of birds.

Krill are important prey across much of the range, with other crustaceans, small fish and squid contributing regionally. Food composition changes with season and ocean conditions. Breeding adults must obtain enough prey for themselves and their chick while repeatedly returning to the colony. Prey capture generally occurs during short, shallow dives, though they are capable of deeper excursions when necessary. The daily energy demands are particularly high during chick-rearing, requiring consistent and successful foraging trips.

Identification

Macaroni penguins have a black face and orange-yellow crest joining across the forehead, unlike white-faced royal penguins and the separated crest lines of rockhopper penguins. Their robust bill is deep orange-brown, and their eyes are a striking reddish-brown, often appearing very dark. The orange-yellow crest feathers are shaggy and extend backwards from the forehead, creating a distinctive bushy appearance.
