Macaroni penguins are one amongst the six species of crested penguins. They have distinct yellow-orange hair over the head; the eyes of macaroni penguins are red. They have pink feet and orange beak. Like any other penguin species, macaroni penguins are flightless carnivore birds. They prey on small aquatic animals.
Macaroni penguins live in Sub-Antarctic islands. They are the largely populated penguins which are estimated to be above 18 million individuals. Macaroni penguins are the biggest and heaviest penguins that reach about 70 cm tall and they were recorded diving to the depth of 100 meters with their dive lasting up to 2 minutes.
Macaroni penguins are the most common species of the penguins in the world that named for its colorful feathers of the golden-orange temple peak. Its scientific name is Eudyptes chrysolophus.
According to the researchers, more than 11 million of the breeding pairs of these penguins inhabit the Southern Ocean. Although the breeding figures of the species are still comparatively high, investigators have observed a distressing decline in these penguins, probably owing to change in climate and its influence on food supplies of penguin.
