Abstract:We identified predators of Spotted Sandpiper (Actitis macularia) nests before and after the establishment of a Common Tern (Sterna hirundo) colony on an island in north-central Minnesota. Migratory Ruddy Turnstones (Arenaria interpres) became major nest predators of the sandpipers after establishment of the tern colony. Turnstones feeding on tern eggs destroyed significantly more sandpiper nests near the colony than far from it. When mink (Mustela vison) were present they were the major nest predators of both sandpipers and terns. However, when the tern colony was present, mink predation of sandpiper nests was reduced significantly. Close proximity of sandpiper nests to those of the terns resulted in both increased and decreased predation, depending on time of year, type of predator, and chance arrivals of occasional predators.
