The Critically Endangered Chinese Crested Tern has always been a rare species and went unseen from 1935 until its re-discovery on the Matsu Islands (off Fujian Province, but controlled by Taiwan) in 2000. It breeds on rocky islets, often among larger colonies of Greater Crested Terns. The most direct threat to it is theft of its eggs for human consumption. The Hong Kong Bird Watching Society, with local chinese groups, is leading an educational campaign to deter egg theft, and the breeding areas which are now known to include islands off the coast of Zhejiang - are being more closely monitored. This photo was taken at the Minjiang Estuary, near Fuzhou.
