Due to a lack of distinctive morphological characters, swift taxonomy and phylogeny has always been an area of disagreement. To shed more light on this subject, we reconstructed swift(let) phylogeny based on 1143 bp of mitochondrial cytochrome-b DNA sequence. Although this is not the first attempt to reconstruct swift phylogeny using molecular data, our results show higher support for many of the branches due to our much longer sequences. However, placement of Hydrochous is still unexpected. Implementation of more conservative genetic regions and sampling of more taxa could solve this problem. Most importantly, the Collocaliini resolve as a monophyletic group. The internal structure of the group shows that non-echolocating Collocalia and echolocating Aerodramus form two distinct clades. This is in congruence with earlier classifications based on morphological characters, but in contrast with more recent classifications.
由于缺乏独特的形态特征，雨燕的快速分类和系统发育一直是一个存在争议的领域。为了更清楚地了解这个问题，我们基于1143个碱基对的线粒体细胞色素b DNA序列重建了雨燕（属）的系统发育。虽然这不是首次尝试使用分子数据重建雨燕的系统发育，但我们的结果表明，由于我们的序列长得多，许多分支得到了更高的支持。然而，水雨燕属的位置仍然出人意料。采用更保守的基因区域和对更多分类单元进行采样可能会解决这个问题。最重要的是，侏金丝燕族被确定为一个单系类群。该类群的内部结构表明，非回声定位的金丝燕属和回声定位的白腰金丝燕属形成了两个不同的进化枝。这与早期基于形态特征的分类一致，但与最近的分类相反。
