Distribution & Abundance
Distribution: Circumpolar, generally on subantarctic islands, although one colony is known to exist on the Antarctic Peninsula

Population Status: Not globally threatened.
A huge colony is located near Cape Lockyer on Heard Island, where the macaroni penguins build nest on surprisingly steep slopes. Research was conducted on this colony during the 2003/04 expedition, investigating the penguins' role as predators in the region.
Unlike most other penguins, macaronis lay 2 eggs each breeding season. The second egg is bigger than the first and is typically the only one that hatches.
