In this article, the authors combine models of timing and Bayesian revision of information concerning patch quality to predict foraging behavior. Pigeons earned food by pecking on 2 keys (patches) in an experimental chamber. Food was primed for only 1 of the patches on each trial. There was a constant probability of finding food in a primed patch, but it accumulated only while the animals searched there. The optimal strategy was to choose the better patch first and remain for a fixed duration, thereafter alternating evenly between the patches. Pigeons were nonoptimal in 3 ways: (a) they departed too early, (b) their departure times were variable, and (c) they were biased in their choices after initial departure. The authors review various explanations of these data.
在本文中，作者结合了时间模型和关于斑块质量信息的贝叶斯修正模型来预测觅食行为。鸽子通过在实验箱中啄击两个按键（斑块）来获取食物。每次试验中，只有一个斑块有食物提示。在有提示的斑块中找到食物有一个固定概率，但只有动物在那里搜寻时食物才会累积。最优策略是先选择较好的斑块并停留固定时长，此后在两个斑块之间均匀交替。鸽子在三个方面表现非最优：（a）它们过早离开，（b）它们的离开时间可变，以及（c）它们在最初离开后选择存在偏差。作者回顾了对这些数据的各种解释。
