Over 800 relict gulls were spotted in north China's Inner Mongolia Autonomous Region.

The black-headed gull is a globally endangered migratory bird species, and is under first-class state protection in China. It breeds throughout central and northern Asia, including in Mongolia and northeastern China.

The name "relict" refers to a plant or animal species that has survived the ancient times and was once a diverse and widespread population.
