Recently published research finds that Marsh Wrens with western songs and eastern songs can nest in the same marsh and still maintain their genetic "purity". Western singers and eastern singers nesting in the same marsh do not interbreed. It seems likely that a split will be coming.
Do you have these two future species "in the bank"?
