摘要：

The information that social foragers use to estimate the quality of food patches might include (1) patch-sample information alone, or it might be used in combination with (2) pre-harvest and/or (3) public information. Four possible patch-assessment strategies resulting from combinations of these sources of information make different predictions concerning how individual foraging success should influence patch persistence and the order of patch departure of individuals in the group. Laboratory data on pairs of budgerigars, Melopsittacus undulatus, are consistent with the hypothesis that these birds combine patch-sample and pre-harvest information to estimate the quality of artificial resource patches. © 1993 The Association for the Study of Animal Behaviour.
