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 …

The popularity of bioacoustics for threatened species monitoring has surged. Large volumes
of acoustic data can be collected autonomously and remotely with minimal human effort. The …

A long‐standing question in animal communication is whether signals reveal intrinsic
properties of the signaller or extrinsic properties of its environment. Alarm calls, one of the …

Begging by nestling birds has been used to test evolutionary models of signalling but theory
has outstripped evidence. Eavesdrop** predators potentially impose a cost on begging …

Birds raise their young under constant risk of predation, which shapes how parents and
young communicate acoustically. Nestling begging calls extract care from parents but …

Abstract Models of parent–offspring conflict and nestling begging honesty often assume that
signaling is associated with increased predation risk. However, little evidence exists that …

Fear itself (perceived predation risk) can affect wildlife demography, but the cumulative
impact of fear on population dynamics is not well understood. Parental care is arguably what …

Parent birds often give alarm calls when a predator approaches their nest. However, it is not
clear whether these alarms function to warn nestlings, nor is it known whether nestling …

Parents of many bird species produce alarm calls when they approach and deter a nest
predator in order to defend their offspring. Alarm calls have been shown to warn nestlings …
