The common gull is a medium-sized pale-grey gull with a rounded head, relatively small yellow-green bill and white-spotted black wingtips. It breeds across northern Eurasia and North America and migrates toward coasts and milder inland areas. Flocks probe grassland for worms and insects, take fish from water and scavenge refuse, while nesting on ground, roofs or cliffs (Wikipedia, general species account). It is Nationally Least Concern (Thailand Red Data 2025).
