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 …

We review the concepts and research associated with measuring fear and its consequences
for foraging. When foraging, animals should and do demand hazardous duty pay. They …

From bird flocks to fish schools, animal groups often seem to react to environmental
perturbations as if of one mind. Most studies in collective animal behavior have aimed to …

The author shares some lessons learned from a lifetime of working with and thinking about
groups. Three types of groups are described, including the impact they have on the …

Mammalian predator-prey systems are behaviorally sophisticated games of stealth and fear.
But, traditional mass-action models of predator prey dynamics treat individuals as …

The story of this edition is a testament to an almost legendary gure in theoretical ecology
and to the in uence his work and charisma has had on the eld. It is also a story that can only …

My objective here is to provide a comprehensive review of recent empirical and theoretical
work on antipredator decision making. The ways in which predators influence the behavioral …

A reduction in individual vigilance with an increase in group size is one of the most
frequently reported relationships in the study of animal behaviour. It has been argued that …

To balance conflicting demands for food and safety from predation, feeding animals have
two useful tools. First, they can vary the amount of time they devote to harvesting patches …

In the study of behavioral predator–prey interactions, predators have been treated as
abstract sources of risk to which prey respond, rather than participants in a larger behavioral …
