Nest defense by Iberian azure-winged magpies (Cyanopica cyanus): do they recognize the threat of brood parasitism?

particular location for nesting from all possible sites (Burger 1985). The exact location of a nest may have important consequences for breeding success, for example influencing predation risk (Regehr et al. 1998) or probability of flooding (Lauro & Burger 1989). Consequently, birds carefully choose nest-sites in order to maximize their possibilities of a successfully breeding outcome. Nest-sit...

The azure-winged magpie (Cyanopica cyanus), has long presented a puzzle for biologists. The naturalist Alfred Wallace was one of the first to consider it. The puzzle lies in its extraordinary distribution. It exists in two distinct locations: Iberia and eastern Asia, 9,000 kilometres apart. Two alternative theories have been put forward to explain this curious distribution. The first proposes t...
متن کاملDoes nest-site selection influence bobwhite nesting success in’south Florida?
Context. Nest-site selection can influence nesting success, and thus population dynamics, of many species of groundnesting birds. Despite the economic importance as a game species, populations of northern bobwhites have been declining throughout the southernUnited States. This paper reports the nesting ecology of northern bobwhites (Colinus virginianus) on Babcock-Webb Wildlife Management Area,...
