Seen on Nightingale island, part of Tristan da Cunha Islands
Sexy crest!!! This is actually a Northern Rockhopper Penguin Eudyptes moseleyi, identified by their more elaborate crests and occurring on the Tristan da Cuhna archipelago (Atlantic) and Amsterdam Island (Indian O.).
The Northern Rockhopper Penguin, Eudyptes c. moseleyi, is usually considered a subspecies of rockhopper penguin, although fairly recent studies show evidence of distinction from the Southern Rockhopper Penguin group Eudyptes c. chrysocome/E. c. filholi.
