We aimed to show how the choice of different methodological and ecological approaches can affect conclusions in nest-site selection studies along different Palearctic meta-populations of an indicator species. First, a multivariate analysis of the variables affecting nest-site selection in a breeding colony of cinereous vulture (Aegypius monachus) in central Spain was performed. Then, a meta-analysis was applied to establish how methodological and habitat-type factors determine differences and similarities in the results obtained by previous studies that have modelled the forest breeding habitat of the species. Our results revealed patterns in nesting-habitat modelling by the cinereous vulture throughout its whole range: steep and south-facing slopes, great cover of large trees and distance to human activities were generally selected. The ratio and situation of the studied plots (nests/random), the use of plots vs. polygons as sampling units and the number of years of data set determined the variability explained by the model. Moreover, a greater size of the breeding colony implied that ecological and geomorphological variables at landscape level were more influential. Additionally, human activities affected in greater proportion to colonies situated in Mediterranean forests. For the first time, a meta-analysis regarding the factors determining nest-site selection heterogeneity for a single species at broad scale was achieved. It is essential to homogenize and coordinate experimental design in modelling the selection of species' ecological requirements in order to avoid that differences in results among studies would be due to methodological heterogeneity. This would optimize best conservation and management practices for habitats and species in a global context.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Alonso, J A</style></author><author><style face="normal" font="default" size="100%">Muñoz-Pulido, R</style></author><author><style face="normal" font="default" size="100%">Bautista, L M</style></author><author><style face="normal" font="default" size="100%">Alonso, J C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Nest-site selection and nesting success in the Azure-winged Magpie in Central Spain</style></title><secondary-title><style face="normal" font="default" size="100%">Bird Study</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Canopy</style></keyword><keyword><style  face="normal" font="default" size="100%">Cyanopica cyana</style></keyword><keyword><style  face="normal" font="default" size="100%">Evergreen and deciduous species (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">Nest site selection</style></keyword><keyword><style  face="normal" font="default" size="100%">Nesting success</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1991</style></year></dates><publisher><style face="normal" font="default" size="100%">Taylor &amp; Francis</style></publisher><volume><style face="normal" font="default" size="100%">38</style></volume><pages><style face="normal" font="default" size="100%">45-51</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Nest-site selection and nesting success in Azure-winged Magpies Cyanopica cyana were studied in 1986 in central Spain. Preferred nest sites were a nonrandom subset of the available habitat. Nests built on evergreen trees had significantly earlier clutch initiation dates than those built on deciduous trees. Birds selected larger trees of each species for nesting, but nests built on very high trees had significantly lower nesting success. Birds tended to locate their nests in a central position relative to the canopy height and as far from the main trunk as possible, without being of the periphery. This may minimize nest accessibility and maximize concealment. Nesting success was higher in the preferred regions of the tree canopy. Predation and inclement weather were probably the factors selecting for the observed patterns in nest-site distribution.</style></abstract><notes><style face="normal" font="default" size="100%">doi: 10.1080/00063659109477066</style></notes><research-notes><style face="normal" font="default" size="100%">doi: 10.1080/00063659109477066</style></research-notes></record></records></xml>
