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.

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

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.

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.

Artificial Nest Experiments: Effects of Nest Appearance and Type of Predator

The Condor, 1987
Nest 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

Effects of nest features and surrounding landscape on predation rates of artificial nests

Bird Study, 1999
Artificial nest predation experiments were carried out in northern Italy in woods which varied in size, isolation and surrounding landscape structure. Multivariate analyses, including logistic regression, showed that: (1) size and isolation of woods did not significantly affect predation rates; (2) nests on the edge of woods did not suffer higher ...
