HONOLULU (AP) - State officials are crediting predator-proof fencing with a record number of wedge-tailed shearwater seabirds hatching at Oahu's Kaena Point Natural Area Reserve.
Hawaii News Now reported that Marigold Zoll of the Department of Land and Natural Resources calls the fence's success "astonishing."
Pacific Rim Conservation biologist Lindsay Young said that the 2012 hatching population is nearly 3,300, more than double the number seen in 2007.
The Laysan Albatross, which also nests at Kaena Point, has also increased in numbers, up by 15 percent to 400 birds.
The shearwaters are particularly vulnerable to non-native predators like dogs and cats because they nest in the ground.
Before the fence was installed in March 2011, predators would kill up to 15 percent of Kaena Point's shearwater chicks each year.
