Significant correlations (P<0.05) between meals and preceding intervals were shown more often by Japanese quail when fed on diluted mash (40% cellulose) than with undiluted mash or pellets. They showed significant correlations between meals and succeeding intervals with about the same frequency on all three foods. Most of the correlation coefficients were low, but experiments in which interval length and meal size were manipulated artificially confirmed that close relationships between meals and intervals can occur, and appear to verify the existence of short-term hunger and satiety mechanisms. Possible explanations for the low correlation coefficients shown by several bird species are discussed, and it is concluded that meal-eating is controlled by a very flexible system. There is no evidence that the timing of meals depends on fixed set points, and it is suggested instead that degrees of hunger and satiety may determine the probabilities of a meal starting or stopping, such a system being associated with emptying and filling of parts of the digestive tract.
与未稀释的粉料或颗粒料相比，以稀释的糊状饲料（40%纤维素）喂养时，日本鹌鹑在进食与之前的间隔时间之间表现出更频繁的显著相关性（P<0.05）。在这三种食物上，它们在进食与后续间隔时间之间表现出显著相关性的频率大致相同。大多数相关系数较低，但人为操纵间隔时间长度和进食量的实验证实，进食与间隔时间之间可能存在密切关系，这似乎验证了短期饥饿和饱腹感机制的存在。文中讨论了几种鸟类相关系数较低的可能原因，并得出结论：进食是由一个非常灵活的系统控制的。没有证据表明进食时间取决于固定的设定点，相反，有人认为饥饿和饱腹感的程度可能决定进食开始或停止的概率，这样一个系统与消化道部分的排空和充盈有关。
