Macaroni penguins are known to be the largest single consumer of marine resources among all of the seabirds, with an estimated take of 9.2 million tonnes of krill a year. [25] Outside the breeding season, macaroni penguins tend to dive deeper, longer, and more efficiently during their winter migration than during the summer breeding season.
Other penguin species breeding on Zavodovski include more than 50,000 macaroni penguins [40] which form small colonies within chinstrap penguin colonies, [44] and gentoo penguins. The size of the penguin colony on Zavodovski appears to be increasing. [45] King penguins also visit the island [46] and may breed there.

There are five penguin species breeding on the islands, king penguins, southern rockhopper penguins, magellanic penguins, gentoo penguins, and macaroni penguins. [16] Approximately 494,500 breeding pairs are thought to live on the island, 500 of which are king penguins. [1]
Chinstrap penguin. Penguins are birds in the family Spheniscidae in the monotypic order Sphenisciformes. [1] They inhabit high-productivity marine habitats, almost exclusively in the Southern Hemisphere; the only species to occur north of the Equator is the Galapagos penguin.
A large number of penguins also breed on the island: in 1978–1979, there were an estimated 117,000, mostly macaroni and chinstrap penguins. However, the penguin population declined at an annual rate of 4.8% from 1979 to 1990, falling to just 62,125 adults, and is thought to have decreased even faster subsequently.
Sphen died earlier this month just before his 12th birthday, the Sydney Sea Life Aquarium said Thursday, a long life for a Gentoo penguin in captivity who can live up to 13 years.
Heard Island is an important breeding site for macaroni, eastern rockhopper, gentoo and king penguins. Endemic species or subspecies are the Heard shag and the black-faced sheathbill. The surrounding waters are home to numerous species of albatross and petrel , some of which breed on the islands, including the endangered southern giant-petrel ...
