|Identification information:||65-75 cm. Large, yellow-crested, black-and-white penguin. Black upperparts. White underparts. Pure white to pale grey cheeks from crest to throat. Long yellow, orange and black plumes project from forehead patch back along crown and droop behind eye. Similar spp. E. schlegeli and Macaroni Penguin E. chrysolophus are the only crested penguins with crests that meet on forehead. E. chrysolophus has jet-black to dark grey cheeks and throat, but light-faced birds are also reported at some sites.|

This species has a large population which is currently thought to be stable, it is confined to just three islands all in close proximity and as such it is susceptible to the effects of human activities or stochastic events. However there are currently no obvious threats that could result in the species qualifying for Critically Endangered in a short time period. The species is therefore classified as Near Threatened as it almost meets the requirements for listing as threatened under criterion D2.
|Previously published Red List assessments:||
|Range Description:||This species is confined to Macquarie Island and nearby Bishop and Clerk Islands, Australia. However, small numbers of similar-looking birds appear at other sub-Antarctic islands (such as Kerguelen Island [Duriez and Delord 2012]), indicating that it may breed elsewhere. It was heavily exploited in the 19th century, but has recovered and, in 1984-1985, an estimated 850,000 pairs were breeding on Macquarie, with an earlier count of over 1,000 pairs on Bishop and Clerk. The population is believed to be stable.|

|Population:||In 1984-1985, the breeding population on Macquarie Island was estimated at 850,000 pairs, with an earlier count of over 1,000 pairs on Bishop and Clerk Islands (Garnett and Crowley 2000).
Trend Justification: The population is thought to be stable, although there is no quantitative analysis to support this (Garnett and Crowley 2000, Garnett et al. 2011, R. Gales in litt. 2012).
|Current Population Trend:||Stable|
|Habitat and Ecology:||It nests in huge colonies on bare, level, pebbly, rocky or sandy ground. When breeding, it feeds on euphausiids, fish and squid. Its ecology and movements during the winter when away from the island are unknown (Christidis and Boles 1994).|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||14.1|
|Movement patterns:||Not a Migrant|
|Congregatory:||Congregatory (and dispersive)|
|Major Threat(s):||It has been argued that there is currently no plausible and serious threat to the species (Garnett et al. 2011). On land, rats take some eggs and young. Breeding success can be reduced as a result of disturbance by researchers and tourists. Marine pollution, particularly ingested plastics, kills some birds. Fishing around sub-Antarctic islands may also adversely affect the species, however during the breeding season the species forages in waters near Macquarie Island and in the Exclusive Economic Zone where fishing is strictly regulated (S. Garnett in litt. 2011). The most likely long-term threat is the effect of climate change on sea-surface temperature and food supply. Disease outbreaks represent another potential threat to the species (R. Gales in litt. 2012). Climate change and disease were recently identified as the only current threats to the species (Trathan et al. 2015).|
Conservation and Research Actions Underway
In Australia the species has been evaluated as Near Threatened. Studies of foraging ecology and breeding biology have been completed. Monitoring of breeding population size and success is ongoing. Feral cats have now been eliminated from Macquarie Island. A rodent and rabbit eradication programme was undertaken on Macquarie Island (R. Gales in litt. 2012, Parks and Wildlife Service 2014). As of August 2014 there had been no signs or sightings of rabbits since December 2011, no signs or sightings of rats since May 2011 and no sightings of mice since June 2011 and no signs of them since April 2012 (Parks and Wildlife Service 2014). Tourists on breeding islands are managed to prevent disturbance.
Conservation and Research Actions Proposed
Carry out surveys to obtain an up-to-date population estimate. Determine trends in numbers. Monitor rates and effects of marine debris ingestion. Monitor the effects of fishing. Establish demographic parameters, particularly survival of different age classes. Study the potential impacts of climate change. Implement a biosecurity plan for Macquarie Island (Parks and Wildlife Service 2014).
