The new breeding population and breeding sites were investigated using drones combined with fixed-point observation in 2016 and 2017. 810 relict gulls( about 410 breeding pairs) were counted. The breeding sites are two islands on the lake where the vegetation is sparse. Forty-eight other bird species recorded. Large numbers of chironomids and Damselflies provided prey for the breeding relict gulls. This is a new record for relict gull breeding in China.更多还原
