Humans cooperate to build complex structures with culture-specific architectural styles. However, they are not the only animals to build complex structures nor to have culture. We show that social groups of white-browed sparrow weavers () build structures (nests for breeding and multiple single-occupant roosts for sleeping) that differ architecturally among groups. Morphological differences are consistent across years and are clear even among groups with territories a few meters apart. These repeatable differences are not explained by among-group variation in local weather conditions, bird size, tree height, or patterns of genetic relatedness. Architectural styles are also robust to the immigration of birds from other groups.
人类通过文化特有的建筑风格合作建造复杂的结构。然而，他们并不是唯一建造复杂结构和拥有文化的动物。我们发现，白头文鸟的群居群体（）会建造结构（繁殖用的巢和多个单只栖息的栖木），这些结构在群体之间在建筑上有所不同。形态差异在多年间保持一致，即使在相隔几米的群体之间也很明显。这些可重复的差异不能用群体间当地天气条件、鸟类体型、树高或遗传关系模式的变化来解释。建筑风格也不受来自其他群体的鸟类移民的影响。
