Scientific Name: Eudyptes schlegeli Finsch, 1876

English Royal Penguin
Spanish Pingüino Real
Taxonomic Source(s): del Hoyo, J., Collar, N.J., Christie, D.A., Elliott, A. and Fishpool, L.D.C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Volume 1: Non-passerines. Lynx Edicions BirdLife International, Barcelona, Spain and Cambridge, UK.
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.

Geographic Range [top]

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 South Georgia and Kerguelen Island [Duriez and Delord 2012]), indicating that it may breed elsewhere. 

Countries occurrence:
Argentina; Falkland Islands (Malvinas); South Georgia and the South Sandwich Islands

Population [top]

Population:The species 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 (Garnett and Crowley 2000). The population is believed to be stable.

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
Additional data:
Number of mature individuals:1700000Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
No. of subpopulations:1Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:Yes
No. of individuals in largest subpopulation:100

Habitat and Ecology [top]

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).

Systems:Terrestrial; Marine
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)

Threats [top]

Major Threat(s):

It has been argued that there is currently no plausible and serious threat to the species (Garnett et al. 2011), since rats, rabbits and cats were eradicated in 2014 as part of the Macquarie Island Pest Eradication Project. Breeding success can be reduced as a result of disturbance by researchers and tourists (Trathan et al. 2015). Marine pollution, particularly ingested plastics, kills some birds (Trathan et al. 2015). 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 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). Oil spills may also be important at local scales.

Conservation Actions [top]

Conservation Actions:

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, including a planned population survey in 2016/2017. Feral cats were eradicated from Macquarie Island in 2001, and rodents and rabbits were eradicated in 2014 as a result of the Macquarie Island Pest Eradication Project (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).
