This endangered penguin has been split from the Southern Rockhopper Penguin following a genetic analysis by Jouventin et al. (2006). It differs from its southern cousin in having much longer gold head plumes presenting an outlandish perpetual bad hair day. This species sometimes goes under the name "Northern Rockhopper Penguin" or "Tristan Penguin." A 2009 study found that its population has been reduced by over one million birds on the islands of Tristan da Cunha and Gough; a decline of over 90 percent on both islands. Causes of the decline remain murky but predation by Subantarctic Fur Seals, human disturbance, pollution, introduced predators , overfishing, and climate change have all been implicated.
