الواق الأصفر ( yellow bittern ؛ Ixobrychus sinensis) هو واق صغير. It is of Old World origins, breeding in the northern Indian Subcontinent, east to the Russian Far East, Japan and Indonesia. It is mainly resident, but some northern birds migrate short distances. It has been recorded as a vagrant in Alaska and there is a single sighting in Great Britain, from Radipole Lake, Dorset on November 23, 1962 – however, the British Ornithologists' Union has always considered this occurrence to be of uncertain provenance and currently it is not accepted onto the official British List.

The yellow bittern was formally described in 1789 by Johann Friedrich Gmelin in his revised and expanded edition of Systema Naturae. He placed it with the herons, cranes, storks and bitterns in the genus Ardea and coined the binomial name Ardea sinensis.[2] Gmelin based his description on the "Chinese heron" that had been included by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds. Latham based his description on a collection of Chinese drawings.[3] The yellow bittern is now one of ten species placed in the genus Ixobrychus that was introduced in 1828 by the Swedish naturalist Gustaf Johan Billberg.[4][5] The genus name combines the Ancient Greek ixias, a reed-like plant and brukhomai, to bellow. The specific epithet sinensis is Modern Latin meaning "China".[6] The species is monotypic: no subspecies are recognised.[5]


الوصف
