“…Artificial nests may also be placed by experimenters in positions that make them more susceptible to predation than natural nests (Andrén and Angelstam 1988;Reitsma et al 1990;Martin 1993;Luck et al 1999). In the current study, however, the heights and vegetation densities of artificial and natural nest sites were not significantly different.…”

Abstract. We compared the predation rate on natural nests of the Eastern Yellow Robin, Eopsaltria australis, with the predation rates on four types of artificial nests in a woodland remnant in southern Victoria. The aims of this study were: to compare the overall rates of predation on artificial and natural nests; to determine whether artificial nests accurately reflect the effects of nest-site characteristics on the predation rate of natural nests; and to examine the effects of using different nest types and egg types for artificial nests. The predation rates on artificial nests were significantly greater than those on natural nests. The predation rate was significantly greater on artificially constructed nests than on real, disused Eastern Yellow Robin nests, but there was no difference in the predation rates on artificial nests containing plasticine or Canary, Serinus canarius, eggs. There were no effects of nest-site characteristics on the predation rates on either artificial or natural nests. These results showed that the method of construction of artificial nests can affect the rate of nest predation, and suggest that artificial nests should be made as realistic as possible in order to gain more accurate information on the predation rates on the natural nests they are meant to represent.

“…A utilização de ninhos artificiais tem sido largamente usada para elucidar padrões de predação em ninhos naturais (GIBBS 1991, SEITZ & ZEGERS 1993. Esse procedimento oferece vantagens como a utilização e o controle de variáveis nos desenhos experimentais (REITSMA et al 1990, MARINI et al 1995, além de disponibilizar menor tempo de campo e um número maior de ninhos. Em alguns estudos, pode-se constatar que o sucesso de ninhos naturais e artificiais não diferiu (GOTTFRIED & THOMPSON 1978, ANDRÉN et al 1985.…”

ABSTRACT. A test of the edge effect on predation of natural and artificial bird nests in the Cerrado. The Cerrado is still one of the most important ecosystems in Brazil, even though more than 50% of its area has been altered or converted to pastureland and plantations. Despite its intense degradation, few ecological processes that might affect its biodiversity have been evaluated. The goal of this study was to test the edge effect on the predation rates at natural and artificial nests, at the Ecological Station of Águas Emendadas, Federal District, Brazil. Natural nests were found and monitored every three to four days from September to December of 2004 in the interior and at the edge of the reserve.Artificial nests were placed at four distances from the edge (0, 500, 1000 and 2000 m) in three spatial replicates in September and again in December of 2004. Each nest received one Japanese Quail and one plasticine egg and was monitored every five days, for 15 days. There was no difference between the rates of predation either in the natural nests or in the artificial nests between treatments. For one bird species, Elaenia chiriquensis (Lawrence, 1865), Tyrannidae, daily survival rates in the incubation and in the hatchling period had opposite values between the edge and the interior.Marks on plasticine eggs suggest that birds are the main predators. Estimates of the abundance of two potential nest predators, Cyanocorax cristatellus (Temminck, 1823), Corvidae and Canis familiaris (Linnaeus, 1758), Canidae, revealed no relationship with distance to the edge, nor with predation rates. Brood parasitism of natural nests was similar between the interior (0%) and the edge (3.8% of the nests). The results described here do not support the edge effect hypothesis for nest predation rates on either natural or artificial nests, nor for brood parasitism rates.

“…It is a foliage-gleaning neotropical migrant that feeds heavily on Lepidoptera larvae during the breeding season, builds an open cup nest and is multibrooded . In addition to intensive monitoring of this species' demography , experimental studies have examined its relationships with vegetation structure (Steele 1992), nest predators (Reitsma et al 1990) and food supplies via food reduction (Rodenhouse and Holmes 1992) and food supplementation (Nagy and Holmes 2005). Study of this species is unique in the Northeast in its breadth, duration and intensity.…”

We used three approaches to assess potential effects of climate change on birds of the Northeast. First, we created distribution and abundance models for common bird species using climate, elevation, and tree species variables and modeled how bird distributions might change as habitats shift. Second, we assessed potential effects on high-elevation birds, especially Bicknell's thrush (Catharus bicknelli), that may be particularly vulnerable to climate change, by using statistical associations between climate, spruce-fir forest vegetation and bird survey data. Last, we complemented these projections with an assessment of how habitat quality of a migratory songbird, the black-throated blue warbler (Dendroica caerulescens) might be affected by climate change. Large changes in bird communities of the Northeast are likely to result from climate change, and these changes will be most dramatic under a scenario of continued high emissions. Indeed, high-elevation bird species may currently be at the threshold of critical change with as little as 1°C warming reducing suitable habitat by more than half. Species at mid elevations are likely to experience declines in habitat quality that could affect demography. Although not all species will be affected adversely, some of the Northeast's iconic species, such as common loon and black-capped chickadee, and some of its most abundant species, including several neotropical migrants, are projected to decline significantly in abundance under all climate change scenarios. No clear mitigation strategies are apparent, as shifts in species' abundances and ranges will occur across all habitat types and for species with widely differing ecologies.
