Abstract

Although predator model presentations are frequently used by ornithologists to study parental care, little is known about the effects of presentations on subsequent nesting success. Only one of 113 model presentation studies surveyed from the literature examined the influence of such experiments on nesting success, and this was conducted with Tree Swallows (Tachycineta bicolor), a cavity-nesting species. I conducted a field test to determine whether model presentations affected fledging success of an open-cup nesting species, the Hooded Warbler (Wilsonia citrina). In 1999, I presented predator models at the nests of Hooded Warblers at the Hemlock Hill Biological Research Area in northwestern Pennsylvania. I compared the fledging success of this species in 1999 with fledging success in the four previous years at the same study site when no such tests took place. Predator model presentations during the nestling stage had no effect on fledging success of this species.
