Sterna bernsteini Schlegel, 1863 |
The Chinese Crested Tern (Thalasseus bernsteini, syn. Hermann Schlegel ( June 10, 1804 - January 17, 1884) was a German Ornithologist. Year 1863 ( MDCCCLXIII) was a Common year starting on Thursday (link will display the full calendar of the Gregorian calendar (or a Common In Scientific nomenclature, synonyms are different Scientific names used for a single Taxon. Sterna bernsteini - see Bridge et al. , 2005) is a seabird of the tern family Sternidae, closely related to Sandwich Tern T. Seabirds are Birds that have adapted to life within the marine environment Terns are Seabirds in the family Sternidae, previously considered a subfamily (Sterninae of the gull family Laridae (van Tuinen et al The Sandwich Tern ( Thalasseus sandvicensis, syn Sterna sandvicensis is a Seabird of the Tern family Sternidae sandvicensis and Lesser Crested Tern T. The Lesser Crested Tern ( Thalasseus bengalensis, syn Sterna bengalensis - see Bridge et al bengalensis. It is most similar to the former, differing only in the bill pattern, which is the reverse of the Sandwich Tern's, being yellow with a black tip. From Lesser Crested Tern, which it overlaps in wintering distribution, it can be told by the white rump and paler grey mantle, as well as the black tip to the bill, which seen from up close also has a white point. The larger Greater Crested Tern is also similar, differing in the stouter, all-yellow bill and darker grey mantle and rump, as well as in size. The Greater Crested Tern, Crested Tern or Swift Tern, ( Thalasseus bergii) is a Seabird in the Tern family which nests in dense
It is a critically endangered species, previously thought extinct, with a mere four pairs rediscovered in 2000, nesting in a Greater Crested Tern colony on an islet in the Matsu Islands, just off the coast of Fujian Province, China, and wintering south to the Philippines. An endangered species is a population of an organism which is at risk of becoming Extinct because it is either few in numbers or threatened by changing environmental or predation The Matsu Islands (also Mazu Islands ( are a minor Archipelago of 19 Islands and islets in the Taiwan Strait administered as Lienchiang This article is about the People's Republic of China province Talk People's Republic of China) PEOPLE'S REPUBLIC OF CHINA ARTICLE GUIDELINES The Philippines ( Filipino: Pilipinas, officially known as the Republic of the Philippines (fil ''Republika ng Pilipinas'' RP In the past, it had a wider distribution off the Chinese east coast north to Shandong Province.

The decline is thought to be due to past hunting and egg collection for food. Past protection of this colony may be because of the islands' disputed status, administered by Taiwan but claimed by mainland China, the military sensitivity of the area restricting access.

It is possible that other small colonies may yet be found off the Chinese and Taiwanese coasts; migrant birds have been seen near the mouth of the Pachang River.

Extinction
In 2007 it was estimated that the Chinese crested tern would be extinct in 5 years if authorities would not protect it. In Biology and Ecology, extinction is the cessation of existence of a Species or group of taxa. BirdLife International of Cambridge, England stated that a survey of Chinese experts found that the number of crested terns fell to 50 birds, half the population of 2004. BirdLife International (formerly known as the International Council for Bird Preservation, not to be confused with Birds International) is the international conservation The city of Cambridge (ˈkeɪmbrɪdʒ is a university town and the administrative centre of the county of Cambridgeshire, England England is a Country which is part of the United Kingdom.
