Avian haemosporidian parasites are highly diverse, have a wide range of host specificity, and reveal diverse compatibility with regard to host range and geographical distribution. Therefore, understanding haemosporidian parasite diversity in different host species and different regions is crucial. A survey of the haemosporidian parasite in 186 Godlewski's buntings in Beijing was conducted to compare infection patterns between Godlewski's bunting, local passerines and the global avian host. High prevalence (88.7%) was found in the bunting and displayed annual stability during the research period. Most of the infections were caused by four dominant lineages, three of which were clustered with lineages of morphological species. In comparison with other lineages in local passerines, the dominant lineages were relative specialists. The findings suggest that the compatibility of dominant lineages in the bunting hosts may play important roles in high haemosporidian prevalence, and the narrow host range of the dominant lineages may be due to coevolution between the parasites and host species.
鸟类血孢子虫寄生虫种类繁多，宿主特异性广泛，在宿主范围和地理分布方面表现出多样的适应性。因此，了解不同宿主物种和不同地区的血孢子虫寄生虫多样性至关重要。对北京186只戈氏岩鹀的血孢子虫寄生虫进行了调查，以比较戈氏岩鹀、当地雀形目鸟类和全球鸟类宿主之间的感染模式。在岩鹀中发现了高感染率（88.7%），并且在研究期间表现出年度稳定性。大多数感染是由四个优势谱系引起的，其中三个与形态物种的谱系聚集在一起。与当地雀形目鸟类的其他谱系相比，优势谱系是相对特化的。研究结果表明，岩鹀宿主中优势谱系的适应性可能在血孢子虫的高感染率中起重要作用，优势谱系狭窄的宿主范围可能是由于寄生虫与宿主物种之间的共同进化。
