社会物种与某些其他人保持个体化的关系，尽管在年龄，繁殖状态和群体成员之间的优势地位不断变化，应该能够个体识别。然而，“真正的”个人识别测试，即一个人识别另一个人的独特特征，是罕见的。通常亲属关系和/或熟悉性足以解释二元互动。灰雁群内的复杂关系表明，它们应该能够识别个体，而不管熟悉程度或亲属关系如何。我们测试了六周大的人工饲养的灰狗是否能区分它们的两个兄弟姐妹。我们开发了一个新的实验方案，在这个方案中，鹅被训练将社会兄弟姐妹与几何符号联系起来。随后，在与其中一个符号相关的同胞存在的情况下，用两个几何符号呈现焦点。与目标相关的几何符号的显著选择表明病灶能够区分各个目标。灰雁成功地学会了这个协会的歧视任务，无论遗传相关性或性别的兄弟姐妹的目标。因此，鹅群中的社会关系可能确实是基于对个体同种的独特特征的认识。
Social species that maintain individualised relationships with certain others despite continuous changes in age, reproductive status and dominance rank between group members ought to be capable of individual recognition. Tests of “true” individual recognition, where an individual recognises unique features of another, are rare, however. Often kinship and/or familiarity suffice to explain dyadic interactions. The complex relationships within a greylag goose flock suggest that they should be able to recognise individuals irrespective of familiarity or kinship. We tested whether six-week-old hand-raised greylags can discriminate between two of their siblings. We developed a new experimental protocol, in which geese were trained to associate social siblings with geometrical symbols. Subsequently, focals were presented with two geometrical symbols in the presence of a sibling associated with one of the symbols. Significant choice of the geometrical symbol associated with the target present indicated that focals were able to distinguish between individual targets. Greylag goslings successfully learned this association-discrimination task, regardless of genetic relatedness or sex of the sibling targets. Social relationships within a goose flock thus may indeed be based on recognition of unique features of individual conspecifics.
