Macaroni Penguin

The Macaroni Penguin is a species of penguin found from the Subantarctic to the Antarctic Peninsula. One of six species of crested penguin, it bears a distinctive yellow crest, and the face and upperparts are black and sharply delineated from the white underparts. Its diet consists of a variety of crustaceans, mainly krill, as well as small fish and cephalopods; the species consumes more marine life annually than any other species of seabird. Numbering up to 100,000 individuals, the breeding colonies of the Macaroni Penguin are among the largest and densest of all penguin species. After spending the summer months breeding, penguins disperse into the oceans for six months; a 2009 study found that Macaroni Penguins from Kerguelen travelled over 10,000 km (6,200 mi) in the central Indian Ocean. With about 18 million individuals, the Macaroni Penguin is the most numerous penguin species. However, widespread declines in populations have been recorded since the mid 1970s. These factors resulted in their conservation status being reclassified as vulnerable. (more...)
