Based on recent phylogenomic studies, the three major lineages of modern birds diverged from each other before the Cretaceous- Paleogene (K-Pg) mass extinction event. In contrast, studies of the phylogeny of feather lice on birds, indicate that these parasites diversified largely after this event. However, these studies were unable to reconstruct the ancestral avian host lineage for feather lice. Here we use genome sequences of a broad diversity of lice to reconstruct a phylogeny based on 1,075 genes. By comparing this louse evolutionary tree to the avian host tree, we show that feather lice began diversifying on the common ancestor of waterfowl and landfowl, then radiated onto other avian lineages by extensive host-switching. Dating analyses and cophylogenetic comparisons revealed that two of three lineages of birds that diverged before the K-Pg boundary acquired their feather lice after this event via host-switching.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Data availability&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Data generated during this study are available through the Illinois Databank (https://doi.org/10.13012/B2IDB-0440388_V1)39. Raw read sequences are available in the NCBI SRA database (Supplementary Table 3).&lt;/p&gt;
