When winter is often visited the charred mud (mudflat) wide, burnt sand and estuaries, rarely in the lake.

pressure:
Lands surrounding the Yellow Sea (China, North Korea and South Korea) which is a major stopover location of this species threatened with loss of habitat extent and quality of wetlands caused by pollution, reduced water inland from the rivers and human disturbance. This species is also an impact from the threat of global climate change because of the limited spreading in latitude 10o from the edge of the continent, where 20-50% of the vegetation type in the region were calculated to disappear along with the addition of CO2 doubling element.

Other Information:
An estimated 80% of the total population has declined since the last 10 years, and this is expected to continue in the future.
