越来越明显的是，鸟类从自己的筑巢经验中学习。目前尚不清楚的是，鸟类是否可以通过观察同类的建造来学习。由于社会学习可以让动物在不进行昂贵的试错学习的情况下获得信息，因此初次建造者应该利用有经验的建造者的成功习惯。我们提出了第一次筑巢的男性斑胸草雀与一个熟悉的或不熟悉的同种男性建筑物的颜色的观察员不喜欢的材料。当有机会建造时，观看过熟悉的男性建造的男性将他们的材料偏好转变为熟悉的男性所使用的材料。观察到不熟悉的鸟类的雄性则没有。因此，第一次筑巢者使用社会信息和复制的巢材料的选择时，示威者是熟悉的，但不是当他们是陌生人。因此，个体之间的关系会影响斑胸草雀如何在社会上传播筑巢技能。
It is becoming apparent that birds learn from their own experiences of nest building. What is not clear is whether birds can learn from watching conspecifics build. As social learning allows an animal to gain information without engaging in costly trial-and-error learning, first-time builders should exploit the successful habits of experienced builders. We presented first-time nest-building male zebra finches with either a familiar or an unfamiliar conspecific male building with material of a colour the observer did not like. When given the opportunity to build, males that had watched a familiar male build switched their material preference to that used by the familiar male. Males that observed unfamiliar birds did not. Thus, first-time nest builders use social information and copy the nest material choices when demonstrators are familiar but not when they are strangers. The relationships between individuals therefore influence how nest-building expertise is socially transmitted in zebra finches.
