Brown-headed Gull (Chroicocephalus brunnicephalus) breeds from Ladakh to Mongolia across the Tibetan Plateau and winters largely in the Indian Subcontinent.
In parts of northern and western India, Brown-headed Gull makes up a large proportion of gull flocks that winter in inland and coastal waters.
This animated migration map was created from observations uploaded to the citizen science platform eBird up until 2020. Where present, the inset graph depicts the seasonal likelihood of finding this species (i.e. the proportion of eBird checklists) within its range in India alone. We are grateful to the many birdwatchers around the world who have enabled the creation of this animation by sharing their observations on eBird.
