Abstract: In the past two decades, many researchers have used artificial nests to measure relative rates of nest predation. Recent comparisons show that real and artificial nests may not be depredated at the same rates, but no one has examined the mechanisms underlying these patterns.

Is nest predation density dependent? A test using artificial nests
Canadian Journal of Zoology, 1992Experiments using artificial nests to test whether predation varies with nest density were conducted in a northern hardwood forest in New Hampshire in June 1989. Nests were baited with quail eggs and placed at densities similar to and substantially higher than the range of natural nest densities.

Patterns of Nest Predation on Artificial and Natural Nests in Forests
Conservation Biology, 2004Abstract: 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 a fragmented Afrotropical forest: evidence from natural and artificial nests
Biological Conservation, 2005Abstract Nest predation accounts for a substantial share of nest failure and low reproductive success in most tropical songbirds. Normally, forest fragmentation leads to an increase in nest predation pressure due to reduced cover, fewer (and poorer) nest sites and predator influxes from the surrounding habitats.

The Auk, 2004
Abstract Incubation is an energetically demanding process for parents, in part because of the thermodynamic costs of maintaining egg temperature. One might predict that aspects of nest construction—in particular, the thermodynamic properties of the nesting material and the degree to which the nest provides shelter from the wind—would have important ...

Assessing development impacts on Arctic nesting birds using real and artificial nests
Polar Biology, 2017Arctic Alaska is an important breeding ground for many migratory bird populations. A variety of factors associated with industrial development may impact nesting birds in this region, including increased nest predator populations associated with anthropogenic nesting and perching sites and the availability of anthropogenic food sources.

Factors Influencing Depredation of Artificial Duck Nests
The Journal of Wildlife Management, 1993Because artificial nests can facilitate controlled experiments of nest success, we used them to assess whether human visitation, nest density, vegetation structure, and proximity to habitat edge could affect depredation of duck nests on Yukon Flats National Wildlife Refuge, Alaska.

Artificial Nest Experiments: Effects of Nest Appearance and Type of Predator
The Condor, 1987Nest predation is a primary cause of nesting mortality for many bird species (Skutch 1949, 1966; Nice 1957; Ricklefs 1969; Nilsson 1984). Food limitation and competition also can affect nesting success (see reviews in Martin 1986, 1987). However, the primary role of nest predation in nesting mortality suggests that it can be a strong agent of selection
