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 …

Studies of reproductive rates in raptors can be valuable in assessing the status of raptor
populations and the factors that influence them. Estimates of nesting success and …

This review examines the main developments that have occurred over the past 50 years in
our understanding of three aspects of raptor biology:(1) natural factors that limit breeding …

Collecting information on breeding biology and performance is an important part of many
studies of the population ecology of birds and is often essential in identifying effective …

The techniques of raptor management underwent a decade of intensive research during the
1970s. Raptor conservation, including species protection and management, as well as …

The reproductive success of a population of Blackbirds Turdus merula occupying farmland
and woodland was studied over 3 years to investigate the effects of habitat on breeding …

Whether predators can limit their prey has been a topic of scientific debate for decades.
Traditionally it was believed that predators take only wounded, sick, old or otherwise low …

Reproductive success has been the target of many field studies of birds, because it is
supposed to relate closely to fitness. Nest-predation has been since a long time recognized …

Breeding biology and nesting requirements of Cape Parrots in their natural habitat and in
captivity were investigated. Few nests were found, suggesting that nest-sites are limiting …

Physical characteristics of nest sites are thought to influence their use by birds and the
outcome of breeding attempts. The presence of preexisting nesting structures can also be an …
