New Zealand oil spill threatens seabirds
Posted on: 10 Oct 2011
BirdLife have said that urgent action is needed to avoid an environmental disaster and to minimise seabird deaths as a result of the oil spill off the Bay of Plenty coast.
Forest and Bird (BirdLife in New Zealand) Seabird Advocate Karen Baird said many seabird species are particularly vulnerable now because they are breeding, and she questioned the initial official response to the oil spill off the northern coast of North Island. The container ship Rena is spilling heavy fuel oil after becoming stuck on Astrolabe Reef, near Tauranga, early on Wednesday. The Rena is carrying around 1,700 tonnes of fuel oil and some seabird deaths have already been reported after fuel oil spilled from holes in the ship’s hull.
“We need to ask why booms were not put around this ship yesterday to contain any release of oil. The sea conditions were good and containing the spill is much better than using toxic dispersants on kilometres of oil slick”, she said. “With no containment, we now need to keep seabirds off the slicks before they get contaminated. Having people go out in boats to keep the birds away from the spillage will save more birds and be better than waiting for the bodies or distressed oiled birds to wash up on shore.”
The major risks will be to seabirds such as terns, gulls, gannets, penguins, petrels and shearwaters, which either dive into the water or land on its surface to feed. “Landing in the oil slick is a death sentence for these birds. Their feathers become clogged with oil and they can sink or drown, or be unable to fly. Swallowing even small amounts of oil can be fatal to them or their chicks when they try to feed them”, Baird said.
Australasian Gannets have a large breeding colony on White Island and Fluttering Shearwaters are currently sitting on eggs and feeding at sea in large flocks. Diving-petrel eggs are hatching and the adults will be feeding on krill and small fish to feed them. Great-winged Petrels are breeding on Mt Maunganui and islands in the area, and will be feeding in waters around the ship grounding, while White-faced Storm-petrels are feeding on plankton on the sea’s surface as they prepare to lay their eggs. New Zealand is justifiably known as the seabird capital of the world. A total of 85 species breed in New Zealand and nearly half of these breed nowhere else.
Environmental and conservation organisations are mobilising volunteers to help deal with the effects of the oil spill.
