在自然界中，许多动物建造的结构可以很容易地按照其总体形态（例如长度、体积和重量）进行测量。然而，通过人类建筑师或艺术家设计和建造的结构来捕捉个性更具挑战性。在这里，我们测试了计算机辅助图像纹理分类方法是否可用于描述织巢鸟（Ploceus属）巢穴的纹理变化，以便将巢穴归因于建造它们的个体织巢鸟。我们发现计算机辅助纹理分析方法确实可以为织巢鸟的巢分配签名。我们认为这种方法将成为一种有用的工具，可以用来检查一系列动物结构的个体差异，而不仅仅是巢穴。
In nature, many animals build structures that can be readily measured at the scale of their gross morphology (e.g. length, volume and weight). Capturing individuality as can be done with the structures designed and built by human architects or artists, however, is more challenging. Here, we tested whether computer-aided image texture classification approaches can be used to describe textural variation in the nests of weaverbirds (Ploceus species) in order to attribute nests to the individual weaverbird that built them. We found that a computer-aided texture analysis approach does allow the assignment of a signature to weaverbirds' nests. We suggest that this approach will be a useful tool with which to examine individual variation across a range of animal constructions, not just for nests.
