A description of the relationship between mean food intake rate (MFIR) and group size is
important in assessing the adaptiveness of group living in animals. Several hypotheses …

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 …

Animals use social information in a wide variety of contexts. Its extensive use by individuals
to locate food patches has been documented in a number of species, and various …

The acquisition and use of socially acquired information is commonly assumed to be
profitable. We challenge this assumption by exploring hypothetical scenarios where the use …

Environmental variability poses a range of challenges to foraging animals trying to meet
their energetic needs. Where food patches are unpredictable but shareable, animals can …

We propose that the use of public information about the quality of environmental resources,
obtained by monitoring the sampling behaviour of others, may be a widespread social …

The quality of a bird's breeding site is a primary determinant of its success or failure to
reproduce there. We expect birds to devote considerable effort to acquiring accurate …

Classical models of breeding habitat selection rarely deal with the question of information
gathering for patch quality assessment. In this paper, we present two models comparing the …

I investigated foraging behavior and competition for food between Turkey Vultures
(Cathartes aura) and Black Vultures (Coragyps atratus) in southern Texas. Turkey Vultures …

One foraging strategy that scavengers can employ to discover unpredictable food sources is
to associate directly with predators who inadvertently provide food. The common raven, a …
