Abstract

We report an apparent protective effect of neighboring Sora (Porzana carolina) nests on Red-winged Blackbird (Agelaius phoeniceus) nests in an experimental study. We suggest that quail eggs used in Sora nests acted as a supernormal stimulus drawing Marsh Wrens (Cistothorus palustris), the main predator in the system, from Red-winged Blackbird nests.
