This survey had two parts: a survey of naturally nesting seabirds in 2018, and a survey of urban nesting Gulls in 2019-21.
Mediterranean Gulls - Bob Knight
Herring Gulls - Tony Morris
In Kent, the “natural nesting” part of the census required the survey of all Gulls (Black-headed, Mediterranean, Common, Herring and Lesser Black-backed), Terns (Sandwich, Little and Common), Fulmar and Cormorants, whilst the urban gull component required the survey of Herring and Lesser Black-backed Gulls. For both surveys, methodology was supplied by JNCC.
A full account of the survey and results for Kent can be found in the 2022 Kent Bird Report.
