ddRADseq on Myioborus warblers (captured in the wild)
we used double-digest restriction site-associated DNA sequencing (ddRAD) following Peterson et al. (2012) with modifications from Thrasher et al. (2018). Genomic DNA was digested using the restriction enzymes SbfI and MspI (New England BioLabs, Ipswich, Massachusetts, USA). The genomic libraries were then sequenced on a single HiSeq2500 Illumina lane (100 bp single-end)
