Hybridization among different bird species is relatively common, but the hybridization rate of individuals is not well known. Justyn et al. use data from the citizen science project eBird to assess the individual hybridization rate in birds, showing that 0.064% of individuals are hybrids. The accuracy of this new estimate is affected by potential biases introduced by birdwatchers, such as over‐reporting of rare hybrids and under‐reporting of difficult‐to‐identify hybrids.

摘要：禽类杂交在个体层面上有多普遍？

不同鸟类之间的杂交比较普遍，但个体之间的杂交率并不为人所知。贾斯汀等人。使用来自公民科学项目 eBird 的数据来评估鸟类的个体杂交率，表明 0.064% 的个体是杂交种。这一新估计的准确性受到观鸟者引入的潜在偏差的影响，例如对稀有杂种的高估和对难以识别的杂种的低报。
