Male Quelea were moved between groups to assess whether experience of winning or losing in new groups was correlated with their success in competition over food when they were returned to their original groups. No such effect was found. However, differences in time spent feeding after deprivation and in aggressive behaviour were found between groups depending on whether they were made up from high- or low-ranking individuals. In paired encounters there was no evidence that birds threatened unfamiliar individuals more than familiar ones or that they avoided sitting next to them more than familiar birds. This suggests that individual recognition, if it exists at all in these groups, is not important in their agonistic relationships. The rank birds occupied was correlated with beak colour, a probable measure of androgen levels, and with the amount of food consumed after deprivation. The latter result suggests that the same period of deprivation may affect some individuals more than others and this in turn may lead them to compete more for food.
将雄性红嘴奎利亚雀在不同组之间转移，以评估在新组中输赢经历是否与它们回到原组后在食物竞争中的成功相关。未发现此类影响。然而，根据组内个体等级高低，发现了剥夺食物后进食时间以及攻击行为上的差异。在成对相遇中，没有证据表明鸟类对陌生个体的威胁比对熟悉个体的威胁更大，或者它们比熟悉的鸟类更避免坐在陌生个体旁边。这表明个体识别（如果这些群体中确实存在的话）在它们的争斗关系中并不重要。鸟类所处的等级与喙的颜色相关，喙的颜色可能是雄激素水平的一个指标，并且与剥夺食物后消耗的食物量相关。后一个结果表明，相同的剥夺时间段对某些个体的影响可能比对其他个体的影响更大，这反过来可能导致它们为食物而进行更多竞争。
