An original method for studying cognitive abilities in largely wild passerine birds was developed. Studies of five crossbills (Loxia curvirostra) showed that this approach could be used to assess their ability to form concepts. All five crossbills learned selection rules for the "larger number" feature over the range "1-10." The birds successfully transferred this to stimuli significantly different from those used in training, which were not comparable in terms of all quantitative properties, but only some (only area or number). Only one bird was able to transfer the learned choice rule to multiples in a new range ("10-20"). Thus, the ability of representative small forest passerine birds to form the "larger than" concept was demonstrated.
开发了一种用于研究主要为野生雀形目鸟类认知能力的原创方法。对五只交嘴雀（红交嘴雀）的研究表明，这种方法可用于评估它们形成概念的能力。所有五只交嘴雀都学会了“较大数量”特征在“1 - 10”范围内的选择规则。这些鸟成功地将此规则应用于与训练中使用的刺激物显著不同的刺激物，这些刺激物在所有数量属性方面不可比，但仅在某些方面（仅面积或数量）可比。只有一只鸟能够将所学的选择规则应用于新范围内的倍数（“10 - 20”）。因此，证明了典型的小型森林雀形目鸟类形成“大于”概念的能力。
