Abstract

Houses around the world are built with a variety of materials like timber and brick, depending on a number of factors such as local climate and material availability. Similarly, non-human animals such as birds use diverse materials to build nests. Very little is known about how animals choose nest materials, and how these choices, in turn, affect the function of the nests they build. As an initial attempt to address this question, we investigated the causes and consequences of nest-material use by Dartford warblers Sylvia undata. The warblers breeding in England show considerable variation in nest materials: some nests are made almost entirely of heather, while others contain a lot of grass. We found that warbler use of nest materials were explained by the composition of the local habitats, but no evidence for relationships between nest-material composition and insulation capacity or the breeding performance. Warblers appear to be able to build equally functional nests using whatever materials are readily available in respective habitats. Studying nest-building behaviour of individual species like Dartford warblers could inform how the use of diverse material in animal architecture evolved.

鸟类筑巢材料变化的原因和后果
世界各地的房屋都是用木材和砖等各种材料建造的,这取决于当地气候和材料可用性等许多因素。同样,鸟类等非人类动物也使用各种材料筑巢。关于动物如何选择筑巢材料,以及这些选择如何反过来影响它们建造的巢穴的功能,我们知之甚少。作为解决这个问题的初步尝试,我们调查了达特福德林莺Sylvia undata使用巢穴材料的原因和后果。在英格兰繁殖的莺在筑巢材料上表现出相当大的差异:一些巢穴几乎完全由石南石楠构成,而另一些则含有大量的草。研究发现,莺的筑巢材料的使用可以用栖息地的组成来解释,但没有证据表明筑巢材料的组成与保温能力或繁殖性能之间存在关系。林莺似乎能够在各自的栖息地使用任何现成的材料建造功能相同的巢穴。研究达特福德莺等个体物种的筑巢行为可以了解动物建筑中不同材料的使用是如何进化的。
