No Split for Yellow-rumped Warbler
Lumpers, rejoice! Splitters and armchair tickers, cry into your beer. The Yellow-rumped Warbler will remain the Yellow-rumped Warbler, at least for the foreseeable future, and will not be split into two, three, or even four species. That is, if you believe in the authority of the American Ornithologists Union, which voted down a proposal to split Dendroica coronata 7-4 (with three of the four in favor voting for a two-way split while only one voted for a four-way split).
