Some birds use social cues, such as the presence of conspecifics, when selecting breeding habitat. This phenomenon, known as conspecific attraction, has been well‐documented in migratory species, but has not been assessed for resident species of birds. We used Dupont's Larks (Chersophilus duponti) as a model species to determine if conspecific attraction plays a role in habitat selection by resident species of birds. At our study site in Soria province in central Spain, we monitored two potential habitat patches and one managed site where management actions had provided apparently suitable habitat. At each site, we broadcast recordings of the songs and calls of male Dupont's Larks, and monitored their presence during the breeding season and dispersal period in 2018 using automated recorders and field surveys. No birds were attracted to our study sites. Our results suggest that management of patches of suitable habitat should occur close to areas (within 1 km) already occupied by Dupont's Larks to encourage natural colonization because, based on our results, playback of conspecific vocalizations may not attract the species to new breeding areas. However, additional studies are needed before drawing conclusions about the effectiveness of conspecific attraction for this and other resident species of birds.

用西班牙中部鸣禽的常住物种杜邦的“百灵鸟”检验同种吸引假说

在选择繁殖栖息地时，某些鸟类会使用社交线索，例如存在特定物种。这种现象被称为同种吸引，已经在候鸟中得到了充分证明，但尚未对常驻鸟类进行评估。我们使用了杜邦的百灵鸟（Chersophilus duponti）作为模型物种，以确定同种异型的吸引力是否在鸟类的居所物种选择栖息地中起作用。在西班牙中部索里亚省的研究地点，我们监测了两个潜在的栖息地斑块和一个受管理的地点，那里的管理行动显然提供了合适的栖息地。在每个站点上，我们广播了杜邦雄性百灵鸟的鸣叫和录音，并使用自动记录器和实地调查监测了它们在繁殖季节和2018年传播期间的存在。没有鸟类被吸引到我们的研究地点。我们的结果表明，应该在杜邦百灵鸟已经占领的区域（1公里以内）附近进行适当栖息地斑块的管理，以鼓励自然定居，因为根据我们的结果，特定声音的回放可能不会将该物种吸引到新的繁殖区域。但是，在得出关于该种和其他常驻物种同种吸引作用有效性的结论之前，还需要进行其他研究。
