David on species limits in the Yellow-rumped Warbler complex

I’m tardy to post here that postdoc Dave Toews recently published an ornithologically quite noteworthy paper in the Auk: Ornithological Advances from his PhD work at the University of British Columbia with Darren Irwin. Their study found evidence of strongly heterogeneous genomic divergence between a number of groups in the species complex, which the AOU currently considers a single species. Dave and his co-authors present data that are very likely consistent with the group consisting of at least three distinct species!
