Macaroni penguin Long-term monitoring programs are underway at a number of breeding colonies, and many of the islands that support breeding populations of this penguin are protected reserves. The Heard Islands and McDonald Islands are World Heritage Sites for the macaroni penguin. The macaroni penguin may be being impacted by commercial fishing and marine pollution. A 2008 study suggests the abilities of female penguins to reproduce may be negatively affected by climate- and fishing-induced reductions in krill density. Like most other penguin species, the macaroni penguin is a social animal in its nesting and its foraging behaviour; its breeding colonies are among
