一群自由活动的野鸽被训练去啄按钮，当操作这些按钮时，可以短暂地接触到谷物。尽管一次只有一只鸟可以接触到这些按钮，但这群鸟的啄鸟被视为一个聚集体。当他们在两个按钮之间进行选择时，每个按钮偶尔都会产生谷物，按钮上的啄鸟比例大致等于从按钮上获得的谷物展示的比例。这符合一个在实验室中得到充分证实的关系，即匹配定律。这表明，匹配定律可能适用于高等生物在自然环境中的行为。
A flock of free-ranging wild pigeons were trained to peck at buttons which, when operated, allowed brief access to grain. Although only one bird at a time could have access to the buttons, the pecks of the group were treated as an aggregate. When they chose between two buttons, each of which could occasionally produce grain, the ratios of pecks at the buttons approximately equaled the ratios of the grain presentations obtained from them. This accords with a relation well substantiated in the laboratory, the matching law. It suggests that the matching law may apply to the behavior of higher organisms in natural environments.
