Assortative social interactions based on (sub)species recognition can be a driving force in speciation processes. To determine whether breeding Barn Swallows Hirundo rustica transitiva in Israel behave differentially towards members of their own subspecies, relative to a different, transient subspecies H. r. rustica and two sympatrically breeding species (Sand Martin Riparia riparia and House Sparrow Passer domesticus), we conducted a territory intrusion experiment near active nests using taxidermy models. Females responded less to the models than males, and the patterns of the recorded behavioral response traits co-varied statistically with sub- or species identity of the models, but none showed patterns of response selectivity for con(sub)specific model types only. These results do not support a role for subspecies recognition in the territorial intrusion responses of H. r. transitiva.

基于（亚）物种识别的各种社会互动可能是物种形成过程的驱动力。为了确定在以色列繁殖的家燕是否对不同亚种H. r。的亚种成员表现出不同的反应。Rusta和两个同属繁殖物种（Sand Martin Riparia riparia和House Sparrow Passer domesticus），我们使用动物标本模型在活动巢穴附近进行了区域入侵实验。女性对模型的反应比男性少，并且所记录的行为反应特征的模式与模型的亚种或物种同一性在统计学上有共同的变化，但是没有一个仅显示针对特定（亚）特定模型类型的反应选择性的模式。这些结果不支持在H. r。的领土入侵响应中亚种识别的作用。转运。
