Nest Predation and Nest-Site Selection of a Western Population of the Hermit Thrush
Audubon's Hermit Thrushes (Catharus guttatus auduboni) in central Arizona have a low nesting success (7 to 20%) due almost exclusively to nest predation. We examine the sites chosen for nesting andExpand

Avoid nest predation when predation rates are low, and other lessons: testing the tropical–temperate nest predation paradigm
Nest predation is the most important cause of nest failure in most birds and latitudinal differences in nest predation rates and life histories suggest that nest predation has been influential inExpand

A test of the Skutch hypothesis: does activity at nests increase nest predation risk?
Small clutches in tropical species of passerine birds may be a response to nest predation. The Skutch hypothesis predicts that nest predation increases with activity at nests, and activity at nestsExpand
