| Résumé : | We describe a new predator-prey relationship between Herring Gulls (Larus argentatus) and Chimney Swifts (Chaetura pelagica) at a communal roost in Sault Ste. Marie, ON, Canada. In a season-long study in 2015, we document 38 instances of predation, an estimate which likely underestimates the extent of total predation pressure. Chimney Swifts were captured on-the-wing by Herring Gulls. |
