Nest predation accounts for the majority of nesting failure, and hence there has been strong
selection on behaviour to reduce nest predation, including patterns of nest defence. Here …

Three factors and their interaction effects are increasingly recognized as important
determinants of nest predation: nest concealment, nest height, and predator type. The risk of …

Vocalizing nestlings are vulnerable to eavesdropping by predators, but may reduce risk
through behavioural tactics such as responding with silence to adult alarm calls. Nestlings …

Summary 1 A simple model of relative effects of parental behaviour (parents present vs.
absent) and nest concealment on probability of nest predation was evaluated by measuring …

We examined nest defence behaviour in relation to predator distance and type, and nest
height in three closely related Acrocephalus warblers: moustached warbler, A …

Nest concealment varies strongly within populations of many species. Although some
studies have revealed the beneficial effects of concealment in mitigating predation pressure …

There is growing evidence that birds are able to discriminate different types of nest intruders
and adjust their nest defence behaviour according to intruder dangerousness and distance …

Selection of favourable micro-habitat conditions at nest-sites and nest defence can be
important anti-predatory strategies in open-cup nesting birds. In response to nest predation …

Evolutionary models suggest that the cost of a signal can ensure its honesty. Empirical
studies of nestling begging imply that predator attraction can impose such a cost. However …

Variation in nest predation rates among bird species are assumed to reflect differences in
risk that are specific to particular nest sites. Theoretical and empirical studies suggest that …
