Different nest predator faunas and nest predation risk on ground and shrub nests at forest ecotones: an experiment and a review

Oecologia, 1998
This study examined predator faunas of artificial ground and shrub nests and whether nest predation risk was influenced by nest site, proximity to forest edge, and habitat structure in 38 grassland plots in south-central Sweden. There was a clear separation of predator faunas between shrub and ground nests as identified from marks in plasticine eggs ...

Patterns of Nest Predation on Artificial and Natural Nests in Forests

Conservation Biology, 2004
Abstract:  Artificial nest experiments have been used in an attempt to understand patterns of predation affecting natural nests. A growing body of literature suggests that neither relative rates nor patterns of predation are the same for artificial and natural nests. We studied nest predation and daily mortality

NEST PREDATION IN AN URBANIZING LANDSCAPE:THE ROLE OF EXOTIC SHRUBS [PDF]

, 2004
Nest predation is considered a primary force shaping avian communities, and landscape-scale features (e.g., amount of fragmentation) are generally recognized as factors mediating nest predation.

Black‐capped vireo nest predator assemblage and predictors for nest predation

The Journal of Wildlife Management, 2012
AbstractNest predation is a major limiting factor for songbird productivity, including the federally endangered black‐capped vireo (Vireo atricapilla). However, nest predator information is limited across the range of the black‐capped vireo in central and southwest Texas. We monitored nests in 3 counties within the breeding range of black‐capped vireos

Nest Predation on Woodland Songbirds: When Is Nest Predation Density Dependent?

Oikos, 1999
Nest predation. if density dependent, may structure avian communities by selecting for nest-site characteristics that dilute the predators' perception of nest density (e.g., by increasing the number and types of potential nest sites) thereby reducing losses to predators.

Predator presence may benefit: kestrels protect curlew nests against nest predators

Oecologia, 1995
We studied whether the presence of breeding kestrels (Falco tinnunculus) affected nest predation and breeding habitat selection of curlews (Numenius arquata) on an open flat farmland area in western Finland. We searched for nests of curlews from an area of 6 km2 during 1985-1993.

Predation on nests: a case of apparent competition

Oecologia, 1994
We describe a field experiment designed to evaluate indirect effects in a prey community sharing common predators. A simple prey community was mimicked with two types of artificial nests. Firstly, it was shown that predation rate increased with nest density when only a single prey was present.

Landscape forest cover and edge effects on songbird nest predation vary by nest predator

Landscape Ecology, 2012
Rates of nest predation for birds vary between and within species across multiple spatial scales, but we have a poor understanding of which predators drive such patterns. We video-monitored nests and identified predators at 120 nests of the Acadian Flycatcher (Empidonax virescens) and the Indigo Bunting (Passerina cyanea) at eight study sites in ...

Nest predation in an anthropogenic landscape

The Wilson Journal of Ornithology, 2013
Abstract Wood Thrushes (Hylocichla mustelina) are experiencing widespread population declines. Knowing the relative contribution of predator species to overall rates of nest predation of Wood Thrushes, and understanding how the thrushes are affected by temporal and landscape factors, may be important elements in choosing and devising effective ...

Resolving the urban nest predator paradox: The role of alternative foods for nest predators

Biological Conservation, 2011
Urbanization is a leading cause of species endangerment in the United States; however, certain species thrive in urban habitats. The loss of key predators or the addition of new predators in urban areas could alter the structure of urban communities.
