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.

Cavity nesting in stitchbirds and the use of artificial nest sites

Notornis, 1989
Cavity nesting by Stitchbirds (Notiomystis cincta) was studied on Little Barrier Island by adding artificial nest sites (boxes) in a breeding habitat. The addition of boxes was a test of the theory that the number of breeding pairs of cavity nesting species is limited by the availability of suitable holes for nest sites. Site limitation is also said to

Predation on artificial bird nests in chaparral fragments

Oecologia, 1991
The predation rate of artificial bird nests was measured in disturbed chaparral habitat fragments and at an unfragmented site in coastal San Diego County, California USA. Local extinctions of chaparral birds has been previously shown to occur in these fragments. The predation rate was highest at the unfragmented site.

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.

USING ARTIFICIAL NESTS TO TEST IMPORTANCE OF NESTING MATERIAL AND NEST SHELTER FOR INCUBATION ENERGETICS

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 ...

Nest predation in a fragmented Afrotropical forest: evidence from natural and artificial nests

Biological Conservation, 2005
Abstract 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.

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.

Is nest predation density dependent? A test using artificial nests

Canadian Journal of Zoology, 1992
Experiments 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.
