Another recent split that benefited me was the split between Northern and Southern House Wren. Who knows how many times it will be split again because there are currently 21 known sub-species. I have seen House Wrens in many places but usually I don't bother taking pictures. On my trip to Ushuaia in Argentina on the way to Antarctica, I noticed this one looked different from ours up north so I took a picture. I am now glad I did! The Southern House Wren covers basically the whole map of Central and South America.
