Description
This is a very small species of gull with a length of just 33 cm (13 in) and, among gulls, only the little gull is smaller. Adults have a black hood and nape during the breeding season. It is very pale with a white body, pale grey wings and a narrow black tail band. The legs and short bill are black and the body is squat. Non-breeding birds have a mottled grey hood and nape, and white-tipped wings with black markings on the primaries.

General Info
Distribution Area
Saunders's gull breeds in eastern China and the west coast of Korea. It breeds in saltmarshes dominated by the seepweed (Suaeda glauca). It overwinters in southern China, Hong Kong, Macau, Taiwan, South Korea, southwestern Japan and Vietnam. Its winter habitats are estuaries and aquaculture ponds and some populations move inland to lakes and marshes.
Species Status
The total population of this gull is estimated as being 21,000 to 22,000 individuals and seems to be in decline. The IUCN has rated it as "vulnerable". The main threats it faces are the degradation of its habitat as it is very dependent on saltmarshes dominated by seepweed. In China, Taiwan, South Korea, Japan and elsewhere, saltmarshes are being drained to make way for aquaculture. The introduction of the strong-growing smooth cordgrass (Spartina alterniflora) has also had deleterious effects. The disturbance of adults also results in greater predation on the eggs and chicks.
