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.

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 ...

Predation on Ground-Nesting Birds' Nests in Relation to Predator Densities and Habitat Edge

Oikos, 1986
To study which predators are responsible for nest-losses among ground-nesting birds in boreal forest and how predators utilize different habitats, especially forest/farmland edge, artificial nests were exposed to predators in central Sweden in 1981. A setup which forced nest-robbers to leave foot-prints showed that different avian and mammalian species

How well do predation rates on artificial nests estimate predation on natural passerine nests?

Ibis, 2001
Daily survival rates (DSR) of three nest types were compared among three passerine species in woodland habitats of the Czech Republic in 1998‐99. The species were: Yellowhammer (YH) Emberiza citrinella, Blackcap (BC) Sylvia atricapilla, Song Thrush (ST) Turdus philomelos.

Raptor Predation of Northern Bobwhite Nests

Journal of Raptor Research, 2008
DEPREDACION DE NIDOS DE COLINUS VIRGINIANUS POR AVES RAPACES Colinus virginianus es una especie que anida en el suelo y tipicamente presenta una tasa de perdida de nidos alta. Hasta hace poco tiempo, la determinacion de las causas de perdida de los nidos se basaba en senales diagnosticas poco confiables registradas en los nidos depredados.

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 ...

What do artificial nests tells us about nest predation?

Biological Conservation, 2002
Artificial nests are commonly used to evaluate predation, but the assumption that this method mimics predation on natural nests has seldom been tested. Natural and artificial nests of eastern yellow robins (Eopsaltria australis) were monitored in four, 55-ha plots over two breeding seasons.

Predation on wader nests in Europe

Ibis, 2008
The population declines of waders in Europe are widely considered to have resulted from habitat loss and degradation due to agricultural changes. However, recent empirical evidence suggests that levels of predation on wader nests are unsustainably high in many cases, even in some situations where breeding habitat is otherwise favourable.

Begging Behaviour and Nest Predation

2002
This chapter reviews the literature on the effects of predation on the evolution of begging behaviour. I conclude that there is little evidence for the existence of a present-day predation cost of begging for calls emanating from the nest site in which the calls evolved.
