Taxonomic note

Recent phylogenetic analyses have shown that the species shows little genetic divergence from Royal Penguin populations (Frugone et al. 2018; 2019), suggesting that a reappraisal of the taxonomic status is needed.

Population justification: The global population is estimated at 6.3 million breeding pairs in at least 258 colonies at c.55 breeding sites (Crossin et al. 2013), with key populations on Isles Crozet (2,200,000 pairs, including 1 million on Ilots des Pingouins), Kerguelen (1.8 million pairs), Heard Island (1 million pairs), South Georgia (1 million pairs) and Marion Island (290,000 pairs).

Trend justification: The current global population estimate of 6.3 million breeding pairs (Crossin et al. 2013) represents a 47% reduction over three generations (37 years) on the previous estimate of 9 million pairs (Woehler 1993, Ellis et al. 1998). At South Georgia, c.5 million pairs were estimated in the 1980s, falling to c.2.7 million pairs in the mid 1990s and to <1 million pairs in 2002 (Trathan et al. 1998, 2012; Crossin et al. 2013). Volcanic activity eliminated a colony of c.1 million pairs on McDonald Island, though satellite images show unidentified penguins that may be recolonising Macaronis (Crossin et al. 2013); photographic images from tourist vessels suggest that the penguins are indeed Macaroni Penguins (E.J. Woehler in litt. 2019). Surveys on Heard Island (c.1 million pairs) suggest a decrease owing to losses in some smaller colonies. The population at Marion has decreased by over 30% from 434,000 pairs in 1994-1995 to 290,000 pairs in 2008-2009 (Crawford et al. 2009), and 267,000 pairs in 2012-2013 (Dyer and Crawford 2015). Recent trends at Crozet are unknown, as there has been no assessment since Jouventin (1988). At Kerguelen populations increased by c.1.06% per annum between 1962 and 2014, and have been stable since (CNRS-CEBC unpublished data). Populations in South America may be stable but data are few (Oehler et al. 2008). A rapid ongoing decline is estimated overall.
