Shorebirds are at risk of predation by raptors, particularly during the non-breeding season (Page & Whitacre 1975, van den Hout et al. 2008). Short-billed Dowitchers Limnodromus griseus have few other significant predators during the non-breeding period (Jehl et al. 2001), and observations of predation by taxa other than raptors are unusual, although gulls have been recorded depredating a range of shorebirds (e.g. Weiser & Powell 2011).
In this paper I describe an instance of a Short-billed Dowitcher being killed by a Western Gull Larus occidentalis in coastal Washington.
