The mesoptile plumage, along with internal physiological changes, allows the chick to maintain its own body temperature away from the nest, and both parents are then able to forage at sea. Macaroni penguins rarely forage more than 40km from the nest site during chick-rearing.īy the end of the 24 days, the chicks have developed their mesoptile plumage, with dark grey upperparts and creamy white underparts. The time spent foraging increases as the chicks get larger, and require more food to maintain growth. The chicks are fed on a daily basis, with females leaving the colony in early morning, and returning with food later the same day. The male continues to brood the chick for the first 24 days, while the female collects food for the chick.

Meal sizes for the chicks average around 200g at this stage. On occasions the chick may have to wait for up to a week after hatching to receive its first feed. Regardless of the time spent at sea during incubation, Macaroni penguins always come ashore during daylight. When the male returns to do the third shift, the female goes to sea and does not return until the chicks have hatched. Both parents incubate the eggs during the first shift, after which the male goes to sea, and the female remains to do the second shift alone. Incubation takes about 5 weeks, and incubation duties are divided into three roughly equal shifts. If both eggs are lost Macaronis do not re-lay. Studies have shown that the first egg is often lost prior to the laying of the second egg, making it of little value as a backup. The first egg is not only considerably smaller, but takes longer to incubate, and is rarely successful. The first egg weighs about 93g and the second egg about 150g. Two eggs are laid with a period of 4 to 5 days between the two. Macaroni penguins breed in colonies on rocky coasts and low cliffs, with nesting densities ranging from 0.7 to 1.4 nests per sq.m. Juveniles lack the elegant crests, and have dull brown eyes, and browny black bills. Females are smaller than the males, but have similar plumage. The most distinctive features are the golden yellow crests which extend from the centre of the forehead and sweep backwards above the eyes.
#Macaroni penguin skin
The large reddish brown bill has exposed pink skin at its base the eyes are red and the legs and feet are pink. The head and upperparts are bluish black, and the underparts are white. They are the largest members of the genus Eudyptes. Macaroni penguins are substantially larger than Rockhoppers, having an average length of around 70cm and an average weight of 5.5kg. MACARONI PENGUIN: Drawing by Mike Bingham The Falkland Islands has no actual Macaroni colonies, but does have about 50 breeding pairs breeding amongst Rockhopper penguins. The South American population stands at just 12,000 breeding pairs. The main breeding sites are found on the islands of South Georgia, Crozet, Kerguelen, Heard, McDonald, Prince Edward and Bouvetoya, with other notable colonies in the South Shetlands, South Orkneys and islands off the coast of Southern Chile. The Macaroni penguin has an estimated world population of over 6 million breeding pairs. World Population: 6,000,000 breeding pairs
