Choosing Where to Feed: Choice of Field,n in the availability of prey, climatic factors, predation risk and social factors have all turned out to be important. The interaction between different factors in socially feeding species may be complex, even in those feeding in single-species flocks. In mixed flocks, the situation may be further

Choosing Where to Feed: Choice within Fields,al heterogeneities in an otherwise continuous distribution, such as the occurrence of earthworms in a field. Whichever form it takes, patchiness in food resources has important consequences for the foraging strategies we should expect predators to adopt (e.g. Pyke .. 1977, Krebs 1978, 1979, Krebs an

Time Budgeting and Feeding Efficiency, known, however, that the size and species composition of a flock can influence individual foraging behaviour and feeding efficiency (see Chapters 1 and 5). Effects of flock size and composition may be another reason why plovers did not follow the predictions of our simple optimal-diet model exactly

Since the effect on individual feeding efficiency depends on the size and species composition of the flock, we might expect birds to be selective about the flocks they join or re

That a study of the former can lead to conclusions about the latter is a reflection of the recent, dramatic increase in our understanding of the evolution of animal behaviour, an increase which stems from an integration of ideas from population biology, evolutionar
