Publisher Summary This chapter reviews studies that have analyzed the effects of local
weather and large-scale climate phenomenon on fluctuations in the size of bird populations …

Birds of prey have been, in comparison to other avian groups, an uncommon study model,
mainly due to the limitations imposed by their conservative life strategy (low population …

Summary 1 Territory quality may affect individual fitness and contribute to density‐
dependent reproduction, with repercussions on population regulation. We investigated the …

The main objective of many conservation programs is to increase population size by
improving a species' survival and reproduction. However, density dependence of …

Summary 1 The hypothesis of site‐dependent population regulation predicts that birds
utilize available nesting sites in a pre‐emptive (ideal despotic) manner, leading to density …

Protected natural areas deserve the combination of nature uniqueness and conservation
willing. The foundation stone for National Parks is the awareness of that unique character …

Summary 1 Reintroductions are commonly used for re‐establishing self‐sustainable
populations in formerly inhabited areas. Reintroductions are expensive, and thus, it is worth …

Nest site selection can have important fitness consequences in birds. I analysed the habitat
characteristics of 392 nests of two sympatric raptor species (common buzzard Buteo buteo …

Raptors are limited by suitable breeding habitat, and they have specific nest-site
requirements. Habitats of high quality presumably have the resources required to sustain …

1. Spatial heterogeneity of resources may influence competition among individuals and thus
have a fundamental role in shaping population dynamics and carrying capacity. In the …
