Chroicocephalus brunnicephalus (Brown-headed Gull)

Synonyms: Larus brunnicephalus (homotypic)

Wikipedia Abstract

The brown-headed gull (Chroicocephalus brunnicephalus) is a small gull which breeds in the high plateaus of central Asia from Tajikistan to Ordos in Inner Mongolia. It is migratory, wintering on the coasts and large inland lakes of tropical southern Asia. As is the case with many gulls, was traditionally placed in the genus Larus. This is a bold and opportunist feeder, which will scavenge in towns or take invertebrates in ploughed fields with equal relish. This is a noisy species, especially at colonies. \n* Brown-headed gull in flight - Bang Poo, Bangkok \n* At Pangong Tso \n* At Pangong Tso \n* \n*
