几乎所有的鸟类都有筑巢的习惯，而且在不同的鸟类之间和鸟类内部，它们的结构特征也有很大的不同。与其他一些鸟类行为一样，早期学习在产生成年筑巢行为方面可能很重要，这似乎是合理的。为了研究成年人对巢材料的偏好是否与他们早期的生活经历有关，我们通过实验操纵了斑马雀成对建造和抚养小鸡的巢的颜色。然后，我们在这些雏鸟成熟时进行测试，以确定它们是否喜欢它们从那里长出羽毛的巢的颜色，或者喜欢与它们父亲相同的颜色。我们还研究了父亲和他们的儿子建造的巢穴的整体结构，以确定雄性建造的巢穴是否与他孵化的巢穴相似。当雄性和雌性天真的建设配对的成年人和测试他们的巢材料的喜好，他们不喜欢的颜色，他们的纳塔尔巢。当这些雄性被重新配对并再次测试他们的偏好时，大多数雄性更喜欢他们父亲喜欢的颜色（这也是大多数雄性喜欢的颜色）。雄性的巢的结构组件不像他父亲建造的巢，但他父亲的巢也不像彼此。我们没有发现任何证据表明，一只鸟从哪里筑巢的经验会影响他对巢材颜色或第一个巢的结构的偏好。
Nests are built by nearly all bird species and can be extremely varied in their structural characteristics, both within and among species. As with a number of other avian behaviours, it seems plausible that early learning might be important in producing adult nest-building behaviour. To examine whether preferences that adults have for nest materials are related to their early-life experience, we experimentally manipulated the colour of the nest in which Zebra Finch pairs built and raised chicks. We then tested these chicks at maturity to determine whether they preferred the colour of the nest from which they had fledged or preferred the same colour as their father. We also examined the overall structure of nests that fathers and their sons built to determine whether the nest a male builds resembles that from which he hatched. When males and females naive to building were paired as adults and tested for their nest material preferences, they did not prefer the colour of their natal nest. When these males were re-paired and their preference tested a second time, the majority then preferred the colour that their father had preferred (which was also the colour preferred by most of the males). The structural components of a male's nest did not resemble the nest built by his father, but neither did his father's nests resemble each other. We found no evidence that the experience of the nest from which a bird fledges influences his preferences for the colour of nest material or the structure of his first nest.
