Conservation workers have found hundreds of oiled northern rockhopper penguins (Eudyptes moseleyi) after a cargo vessel wrecked on Nightingale Island, apart of the UK’s Tristan da Cunha archipelago. Northern rockhopper penguins are listed as Endangered by the IUCN Red List. According to a press release by BirdLife International, the spill threatens nearly half of the world’s northern rockhopper population.
Tristan Conservation Department deployed nine employees to the remote island to investigate the damage. They found an “awful scene” with an oil slick ranging “from thin films of oil, small balls and larger clumps of tar with the smell of diesel everywhere,” according to the Department. The team is “busy doing what they can to clean up northern rockhopper penguins presently coming ashore smothered in oil on Nightingale Island.”
The oil slick is currently 8 miles (13 kilometers) long and threatens other sea birds and wildlife, as well as a fishery.
“The consequences of this wreck could be potentially disastrous for wildlife and the fishery-based economy of these remote islands. The Tristan da Cunha islands, especially Nightingale and adjacent Middle Island, hold million of nesting seabirds as well as four out of every ten of the world population of the globally endangered Northern Rockhopper Penguin,” Richard Cuthbert, a Royal Society for the Protection of Birds (RSPB) biologist who has spent time on Nightingale Island, told BirdLife International.
The wreck raises the specter of another threat: rats. Nightingale Island is home to a variety of nesting seabirds and currently free of any land mammals. However it’s likely the crashed craft was carrying rats, which, if they invade the island, would further endanger the nesting birds.
Two nearby islands, Inaccessible Island and Gough Island, have been designated World Heritage Sites by UNESCO due to large populations of seabirds and endemic species. The oil could threaten Inaccessible Island which lies close to Nightingale.
A tugboat is set to arrive today to remove the broken craft and deliver environmental specialist Estelle van der Merwe, who has worked with oiled birds in the past.
All 22 employees of the wrecked cargo craft are safe.

The penguin crisis: over 60 percent of the world’s penguins threatened with extinction
(06/10/2010) Everyone loves penguins. With their characteristic black-and-white ‘tuxedo’ markings, upright waddle, and childlike stature, penguins seem at once exotic and familiar: exotic because they live far from most human habitations, familiar because they appear innumerable books and movies. From Mr. Popper’s Penguins to Happy Feet, and from March of the Penguins to And Tango Makes Three, penguins pop-up everywhere. The flightless birds have even provided the name and symbol to one of the world’s most successful publishing houses. Yet despite their popularity amid the human kingdom, few people seem aware that penguins worldwide are facing an extinction crisis.
Rockhopper penguins benefit from new park in Argentina
(03/31/2010) Southern rockhopper penguins (Eudyptes chrysocome) are easily distinguished by the spiked plumes on their head, their neon-yellow eyebrows, and red eyes. But these wild-looking penguins are also endangered: the IUCN Red List classifies them as Vulnerable to extinction due to pollution and drowning by fishing nets.
