  • Abstract A Red-tailed Hawk (Buteo jamaicensis; estimated mass 1,000–1,200 g) failed to kill a Red-breasted Merganser (Mergus serrator; estimated mass 1,150 g) that it captured in shallow water (<25 cm), but evidently dispatched a starving Red-necked Grebe (Podiceps grisegena; mass 645–660 g). These observations are pertinent to estimating the upper mass limit for successful foraging in water.
