Studies on the contribution of the yellow-necked mouse Apodemus flavicollis and of other vertebrates to the diet of the tawny owl Strix aluco were carried out in Warsaw (central Poland) in the years 1983–2018. The frequency of the yellow-necked mouse in owl pellets increased at the break of the 20th and 21st centuries, particularly in some woodlands in the peri-urban area of the agglomeration. In the second half of the first decade of the twenty-first century, this mouse species colonised a park in the city centre. The yellow-necked mouse may become an important competitor for the synurbic population of the striped field mouse Apodemus agrarius.

1983-2018年间，波兰华沙集聚区的一些林地里，黄颈老鼠Apodemus flavicollis的种群增加和同化

在1983-2018年间，在华沙（波兰中部）进行了黄颈小鼠黄线姬鼠和其他脊椎动物对黄褐色猫头鹰Strix aluco饮食的贡献的研究。在20世纪和21世纪初，猫头鹰颗粒中黄颈鼠的出现频率增加，尤其是在城市群周边地区的一些林地中。在二十一世纪前十年的下半叶，这种老鼠定居在市中心的一个公园。黄颈小鼠可能成为条纹田鼠黑线姬鼠协同种群的重要竞争者。
