Data from: A bee or not a bee: an experimental test of acoustic mimicry by hoverflies
- 负责人：
- Moore, Christopher D.
- DOI：
- doi:10.5061/dryad.81jh5
- 摘要：
- reduces predation on artificial prey by wild birds, but that the hoverfly mimic alarm sound does not. Finally, we trained chicks to avoid distasteful food
Data from: Seabirds vary responses to supplemental food under dynamic natural prey availability and feeding aggregation composition
- 负责人：
- DOI：
- doi:10.5061/dryad.rr4g39b
- 摘要：
- experimental period), along with 10-min control periods before and after. We recorded the species-specific number of birds on the water, the number of birds
Data from: Earthworm activity and availability for meadow birds is restricted in intensively managed grasslands
- 负责人：
- DOI：
- doi:10.5061/dryad.0gn43fr
- 摘要：
- 1. Earthworms are an important prey for the endangered meadow birds of north-west Europe. Although intensive grassland management with high manure
Data from: Validating the incorporation of 13C and 15N in a shorebird that consumes an isotopically distinct chemosymbiotic bivalve
- 负责人：
- DOI：
- doi:10.5061/dryad.c25gd
- 摘要：
- h chemosynthesis-based prey. The experiment showed that neither the isotopic discrimination factor, nor isotopic turnover time, differed between birds consuming
Data from: Transparency reduces predator detection in mimetic clearwing butterflies
- 负责人：
- DOI：
- doi:10.5061/dryad.17pk7v8
- 摘要：
- exhibiting different degrees of transparency, ranging from fully opaque to largely transparent. We tested our prediction using both wild birds and humans

- DOI：
- doi:10.5061/dryad.7v6q3
- 摘要：
- for a variety of functions, such as communication and predator/prey detection. Using a comparative approach with 308 populations of 183 bird species from 14
Data from: Foraging at the edge of the world: low?altitude, high?speed maneuvering in barn swallows
- 负责人：
- DOI：
- doi:10.5061/dryad.4v5r8
- 摘要：
- aerial performance of birds in a natural state. We undertook the present study to test: (i) the manner in which barn swallows (Hirundo rustica) may exploit
Data from: Digestive capacity and toxicity cause mixed diets in red knots that maximize energy intake rate
- 负责人：
- DOI：
- doi:10.5061/dryad.5fp4g
- 摘要：
- diet choice in red knots (Calidris canutus canutus) feeding on mollusks at a West-African wintering site. At this site, the birds fed primarily on two species
Data from: The evolution of colour polymorphism in British winter?active Lepidoptera in response to search image use by avian predators
- 负责人：
- DOI：
- doi:10.5061/dryad.s62ks69
- 摘要：
- colouration of these species represents an anti?search image adaptation against birds. To test (a) for search image driven apostatic selection, dimorphic
Data from: Free-ranging farm cats: home range size and predation on a livestock unit in Northwest Georgia
- 负责人：
- DOI：
- doi:10.5061/dryad.v3n85
- 摘要：
- mammals were Peromyscus sp., Sylvilagus sp. and Microtus sp. Invertebrates and birds were less important as prey, but all mammalian prey identified
