Twenty-eight STR loci were screened in wild populations of six bird of prey species providing allele frequencies and population genetic parameters necessary for the application of STRs in wildlife forensic genetic casework. Individual STR loci were validated according to forensic recommendations in specimens of golden eagle (Aquila chrysaetos), goshawk (Accipiter gentilis), merlin (Falco columbarius), peregrine falcon (Falco peregrinus), gyr falcon (Falco rusticolus) and saker falcon (Falco cherrug). Deviations from Hardy-Weinberg expectations and linkage disequilibrium between locus pairs were examined. The average probability of identity (PI(ave)) and power of exclusion (PE) suggest the profiling systems of golden eagle, goshawk, merlin and peregrine falcons are capable of providing robust and highly discriminatory forensic evidence for legal proceedings. Due to low sample numbers the allele frequency data for gyr and saker falcons is not currently capable of providing an effective probability of identity. Further work should focus on increasing the size of these data sets.
在六种猛禽的野生种群中筛选了28个STR基因座，提供了在野生动物法医遗传学案件工作中应用STR所需的等位基因频率和群体遗传参数。根据法医建议，在金雕（Aquila chrysaetos）、苍鹰（Accipiter gentilis）、矛隼（Falco columbarius）、游隼（Falco peregrinus）、矛隼（Falco rusticolus）和猎隼（Falco cherrug）的样本中对各个STR基因座进行了验证。检查了与哈迪-温伯格预期的偏差以及基因座对之间的连锁不平衡。平均个体识别概率（PI(ave)）和排除概率（PE）表明，金雕、苍鹰、矛隼和游隼的分型系统能够为法律程序提供可靠且具有高度鉴别力的法医证据。由于样本数量较少，矛隼和猎隼的等位基因频率数据目前无法提供有效的个体识别概率。进一步的工作应侧重于增加这些数据集的规模。
