野鸭（A.（Platyrhynchos L.）分布在2块食物之间，与理想自由模型预测的分布非常接近。这个模型的一个重要假设被违反了，因为一些个体的专制行为导致不同的鸟类获得不平等的回报。鸟类在食物斑块之间的分布受到这些暴君分布的影响。鸭子最初可能使用的频率供应的食物项目在一个补丁，以评估其盈利能力，但在较长的时间使用其他线索。
Mallards (A. platyrhynchos L.) distribute themselves between 2 patches of food in a close approximation to the distribution predicted by the ideal free model. An important assumption of this model is violated since the despotic behavior of some individuals results in different birds receiving unequal payoffs. The distribution of the birds between the food patches is influenced by the distribution of these despots. The ducks probably initially use the frequency of supply of food items at a patch to assess its profitability, but over a longer time use other cues.
