This study examines the habitat selection of grey partridge (Perdix perdix) and the effect of habitat type within partridge home ranges on nest site choice and nest success. Data were collected via radio-tracking in three different areas in the Czech Republic between 2002 and 2010. Compositional analysis was performed on 12 habitat types and uncultivated habitats (such as ruderals, field margins and game refuges) were selected the most during the pre-nesting and nesting periods. Grey partridges tended to nest in uncultivated habitats and avoided nesting in dominant cereal monocultures. We tested six variables that may determine nest site choice and success. Of these, the study area, proportion of selected habitat and habitat diversity (expressed by the Simpson’s diversity index) significantly affected nest placement in uncultivated habitats. Despite this, the lowest nest failure rate was observed in the predominant cereal habitat. Our findings suggest a possible ecological trap for partridges throughout our study areas. Due to the lack of uncultivated habitats, partridges favoured nesting in habitats with a higher predation risk. Conservation managers should increase the proportion of uncultivated areas and promote habitat diversity for partridge populations in central Europe.

栖息地的稀缺形成了欧洲中部农业景观中灰色part（Perdix perdix）的生态圈套

本研究考察了灰part（Perdix perdix）的栖息地选择。）以及part家园范围内栖息地类型对筑巢地点选择和筑巢成功的影响。在2002年至2010年之间，通过无线电跟踪收集了捷克共和国三个不同地区的数据。对12种栖息地类型进行了成分分析，在战前阶段，未耕种的栖息地（如石，田野边缘和野兽避难所）被选为最多嵌套和嵌套期。灰色的tend倾向于在未经耕种的栖息地筑巢，避免在主要的谷物单一栽培中筑巢。我们测试了六个变量，这些变量可能决定巢点的选择和成功。其中，研究区域，选定生境的比例和生境多样性（由辛普森多样性指数表示）显着影响了未耕种生境中的巢穴位置。尽管如此，在主要的谷物栖息地中观察到最低的筑巢失败率。我们的发现表明，在我们整个研究区域内，part可能存在生态陷阱。由于缺乏未开垦的栖息地，part更倾向于在具有更高捕食风险的栖息地筑巢。养护管理人员应增加未耕种地区的比例，并促进中欧part种群的生境多样性。
