研究了斑胸草雀觅食行为中优势度、活动和探索水平对领导行为的影响。在成对的斑胸草雀中，大小相当，经历了相同程度的食物匮乏，同一只鸟在几次试验中一直到达第一个觅食地。同样的食物到达模式发生在两个遥远的补丁同时提供资源时，这种情况可能会让下属更容易获得资源。在进一步的测试中，相同的鸟组成新的配对导致领导权的几次变化，表明领导权不是一个绝对的特征。在独立的、单独的试验中，被证明是最活跃和最具探索性的一对中的一个成员，在几乎所有的休息中都成为了领导者。同样的模式也适用于新重新排列的配对，其中个体经常经历优势地位的变化。在所有的测试中，支配力都没有与领导力联系起来。结果表明，在一个相对平等的物种，活动和探索的水平可能是一个更强的预测领导比优势。
This study investigated the role of dominance and level of activity and exploration on leadership in zebra finches (Taenopygia guttata) searching for food. In pairs of zebra finches Fairly matched in size and that experienced the same level of food deprivation, the same bird consistently reached first one foraging patch over several trials. The same pattern of arrival to food occurred when resources were provided in two distant patches available concurrently, a situation that would potentially allow subordinates a greater access to resources. In further testing, the formation of new pairs with the same birds led to several changes in leadership, indicating that leadership is not an absolute feature. The member of a pair that proved to be the most active and exploratory during independent, solitary trials became the leader in nearly all pairs rested. The same pattern held true in newly rearranged pairs where individuals often experienced changes in dominance status. Dominance failed to be associated with leadership in all tests. The results suggest that in a relatively egalitarian species, level of activity and exploration may be a stronger predictor of leadership than dominance.
