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

Differences in Predators of Artificial and Real Songbird Nests: Evidence of Bias in Artificial Nest Studies

Conservation Biology, 2004
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.

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.

Research on the rearing of bumblebees in artificial nests

Ethology Ecology & Evolution, 1994
Rearing trials on several Bombus species were carried out in 1990 and 1991. The purpose was to improve techniques of colony management and to observe colony growth and the behaviour of foraging workers. A total of 5 queens of Bombus hortorum (L.), 32 of B. humilis Ill., 93 of B. lapidarius (L.), 77 of B. pratorum (L.), 5 of B.

Effects of Nest-Site Selection on Depredation of Artificial Nests

The Journal of Wildlife Management, 1989
We compared depredation of artificial arboreal nests between nests placed at nest sites used by birds in the previous season (actual nests) and those located at random nest sites (random nests) on a ruffed grouse (Bonasa umbellus) management area in central Pennsylvania from May to July 1987.

Suitability of Artificial Nests—Response

Science, 2010
Faaborg presents a valid concern that artificial nests should not be used to infer real nest success. For our study, we chose artificial nests to provide a controlled measure of relative predation risk across latitudes, not to infer real nest success.

Suitability of Artificial Nests

Science, 2010
The Report “Lower predation risk for migratory birds at high latitudes” by L. McKinnon et al. (15 January, p. [326][1]) describes a massive artificial nest experiment spanning 29 degrees of latitude in the high Arctic.

Validity of Using Artificial Nests to Assess Duck-Nest Success

The Journal of Wildlife Management, 1998
Artificial nests have been used in numerous studies of nest success because they can provide adequate sample sizes and be placed in accordance with experimental designs. However, the critical assumption that a strong linear relation exists between success of artificial and natural nests has rarely been tested.
