It has not been seen since 1969. Taxonomy and systematics The nightingale reed warbler was described by the French zoologists ... by some taxonomists. Of this subspecies there never have been reports of a substantial population. In 1982 only four up to possibly 15 birds of the subspecies have been counted, and since 1995 none has been sighted, despite extended efforts to find specimens.

Marquis was a Japanese ornithologist. He was the founder of the Yamashina Institute for Ornithology. Biography Yamashina was born in Kōjimachi, Tokyo, the second son of Prince Kikumaro Yamashina and Princess Noriko (Kujo) Yamashina. Through his mother, a half-sister of the Crown Princess Sadako, he was the nephew of the then Crown Prince Yoshihito, the future Taishō Emperor.

Aguigan
Aguiguan (also Aguigan and Aguihan, based on the Spanish rendition of the native name, Aguijan, which is still used) is a small bean-shaped coralline island in the Northern Mariana Islands chain in the Pacific Ocean. It is situated south-west of Tinian, from which it is separated by the Tinian Channel. Aguiguan and neighboring Tinian Island together form Tinian Municipality, one of the four main political divisions that comprise the Northern Marianas. History It is likely that first sighting by Europeans occurred during the Spanish expedition of Ferdinand Magellan, or by its continuation by Gonzalo Gómez de Espinosa being charted as ''Santo Ángel''. It was visited by the Spanish missionary Diego Luis de San Vitores in 1669. Aguiguan was administered as part of the Spanish Mariana Islands from the 16th century to 1899, when the Northern Marianas were sold by Spain to the German Empire. Under Germany, it administered as part of German New Guinea. During World War I, Aguiguan c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nightingale Reed Warbler
The nightingale reed warbler (''Acrocephalus luscinius''), or Guam reed-warbler, was a songbird endemic to Guam. It has not been seen since 1969. Taxonomy and systematics The nightingale reed warbler was described by the French zoologists Jean Quoy and Joseph Gaimard in 1832 from a specimen collected on the island of Guam in the western Pacific Ocean. They coined the binomial name, ''Thryothorus luscinius''. Until 2011, the Pagan reed warbler, Aguiguan reed warbler, and Saipan reed warbler were considered as subspecies of the nightingale reed warbler until split by the IOC. Threats The nightingale reed warbler was driven to extinction by several introduced species. These included the brown tree snake which has also decimated the populations of several other bird species on Guam. Other introduced predators included rats, cats and feral ungulates such as goats or sheep. An introduced plant, ivy gourd ''Coccinia grandis'', the ivy gourd, also known as scarlet gourd, ...

Acrocephalus (bird)
The ''Acrocephalus'' warblers are small, insectivorous passerine birds belonging to the genus ''Acrocephalus''. Formerly in the paraphyletic Old World warbler assemblage, they are now separated as the namesake of the marsh and tree warbler family Acrocephalidae. They are sometimes called marsh warblers or reed warblers, but this invites confusion with marsh warbler and reed warbler proper, especially in North America, where it is common to use lower case for bird species. These are rather drab brownish warblers usually associated with marshes or other wetlands. Some are streaked, others plain. Many species breeding in temperate regions are migratory. This genus has heavily diversified into many species throughout islands across the tropical Pacific. This in turn has led to many of the resulting insular endemic species to become endangered. Several of these species (including all but one of the species endemic to the Marianas and two endemic to French Polynesia) have already go ...
