ABSTRACT A growing body of work suggests that breeding birds have a significant capacity
to assess and respond, over ecological time, to changes in the risk of predation to both …

Conspecific brood parasitism (CBP) is a reproductive tactic in which parasitic females lay
eggs in nests of other females of the same species that then raise the joint brood. Parasites …

We investigated the behavioural mechanisms and adaptive significance of intraspecific
brood parasitism in wood ducks, Aix sponsa, by observing a colour-marked population in …

1. Hole-nesting birds are frequently faced with a shortage of suitable nest sites in regions of
intensive forest management. Nest boxes are sometimes provided to alleviate nest-site …

The potentially confounded effects of factors affecting breeding dispersal have rarely been
simultaneously examined. The consequences of breeding dispersal are even less studied …

We review the current and future threats to duck populations that breed, stage, moult and/or
winter in the Nordic countries. Migratory duck species are sensitive indicators of their …

Облигатный гнездовой паразитизм зарегистрирован менее чем у 1% видов мировой
фауны птиц. Столь небольшое число видов, для которых характерен такой способ …

Variation in nest concealment is puzzling given the expected strong selection for safe nest
sites. Selecting a concealed nest may decrease the risk of clutch predation but hinder …

Alternative reproductive tactics enable individuals to choose a reproductive tactic relative to
their status and prevailing environmental conditions in a way that increases their fitness. For …

Conspecific nest parasitism (CNP) is a widespread alternative reproductive tactic in birds.
Several hypotheses have been put forward to explain the evolution and occurrence of CNP …
