摘要

在一群8只母鸡中建立了稳定的食物竞争秩序。然后,每只母鸡可以选择竞争对手,在连续10次的竞争试验中,允许它从2个同伴中选择。所有的母鸡都可以选择鸡群中剩下的7只鸟中的每一对。记录了许多具有统计意义的社会歧视。虽然每只鸡的选择总数与竞争等级之间的相关性不高,但当分析个体“支配-从属”选择时,鸟类有明显的倾向避免更高等级的母鸡。受试者还可以评估相对等级,而不仅仅是区分比自己更占优势或更弱势的鸟类。本文讨论了这些发现对家禽竞争顺序解释的意义。

Fowl sociometry: Social discrimination and the behaviour of domestic hens during food competition

A stable food competition order was established in a flock of 8 hens. Each hen was then provided with a choice of competitor by allowing it to choose between 2 of its group-mates in 10 consecutive competitive trials. All hens were given a choice of every possible pairing of the remaining 7 birds in the flock. Many statistically significant social discriminations were recorded. Although there was a low correlation between the total number of choices for each bird and competitive rank, there was a significant tendency for birds to avoid higher-ranking hens when individual “dominant-subordinate” choices were analysed. Subjects could also assess relative rank rather than merely distinguishing between birds more or less dominant than themselves. Implications of these findings for the interpretation of competitive orders in domestic fowl are discussed.
