Abstract: An exceptional case of nest fidelity in a pair of Glaucous-winged Gulls (Larus glaucescens) is described. From 2011 May to 2016 September, the pair was recorded living on and actively defending their nesting territory from conspecifics in downtown Vancouver, B.C. on an almost daily basis, year-round. While gulls are well-known to vigorously defend their nesting territory over multiple years during breeding seasons, it is highly unusual to observe such behaviour in the fall and winter months.
Key words: Glaucous-winged gull, Larus glaucescens, nest fidelity, urban nesting, rooftop nesting, urban ecology
