Population justification: Population trends are still poorly known due to the remote nature of these islands. The global population however is estimated at around 240,300 breeding pairs (Cuthbert 2013, TdC and RSPB unpubl. data) with the majority of breeding pairs being found on Gough Island and islands in the Tristan da Cunha group (68,000 pairs on Middle Island -2015-, 64,700 pairs on Gough -2006-, 16,000 pairs on Nightingale -2015-, 54,000 pairs on Inaccessible -2009- and 3600 pairs on Tristan da Cunha -2015- islands; Cuthbert 2013, RSPB and TdC unpubl. data). Numbers indicate that populations are still declining (TdC and RSPB unpubl. data). At the species’ two breeding locations in the Indian Ocean, Amsterdam (25,000 pairs, 1993) and St. Paul (9,000 pairs, 1993) islands numbers have been declining at an average rate of 3-4% since the early 1970s (CEBC-CNRS unpubl. data). Overall, recent population models indicate that over the past 37 years (three generations) the numbers of Northern Rockhopper Penguins have declined by 57% (Birdlife International 2010). At Amsterdam Island the decline over the past three generations reaches 74% (CEBC-CNRS unpubl. data).
