Yellow-legged Gull, Warks, July 2016.
Here in its ninth calendar year, this YLG first appeared at Kingsbury Water Park as a 3cy individual in January 2010.
It has returned again in July in subsequent years, generally remaining for six months and departing in early to mid-January.
In 2024 it returned for its 16th successive winter (and in its 17th calendar year).
