The effect of habitat edge on avian nesting success has been the focus of considerable debate. We studied relationships between habitat edges, locations of nests, and predation. We tested the ecological trap hypothesis for 5 shrubland bird species in the Missouri Ozarks. We compared habitat selection and daily nest predation rates among 3 distance-to-edge categories. Edge effects were species specific. Indigo bunting (Passerina cyanea) and northern cardinal (Cardinalis cardinalis) preferred nest sites that were close (
