As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Critically Endangered Chinese Crested Tern conservation vital so saving the species

March 2013. In early March, an international workshop in Xiangshan, Zhejiang Province, China, marked the start of an ambitious plan to restore a network of breeding sites for the Critically Endangered Chinese Crested Tern Sterna bernsteini, probably the world's most threatened seabird.

Rediscovered in 2004 - Eggs destroyed by typhoon and thieves
After more than half a century with no breeding records, four adults and four chicks were discovered in 2000 on the Mazu Islands (administered by Taipei) off the coast of China's Fujian Province. In 2004 another colony was found in the Jiushan Islands, off Zhejiang Province, but breeding failed after two typhoons hit the islands. No breeding birds were seen in the Jiushans until 2007, when eight Chinese Crested Terns and about 2,000 Greater Crested Terns returned. But the colony was raided by egg poachers, and terns have not nested there since.

New colony
In 2008 a new colony, believed to be the birds that nested earlier on the Jiushans, was discovered in the Wuzhishan Islands, 80 km to the north. They have returned to nest on the Wuzhishans annually, but nesting space has become limited, and the terns have started using less favourable sites. News of the terns has spread, increasing the risk of disturbance from photographers.
