 * The gnatcatchers are listed under Sylviidae. It should be in Polioptilidae.


 * The Lanceolated Warbler and Middendorf's Grasshopper-warbler are listed under Sylviidae. They should be in Locustellidae.


 * The same thing happened to the Dusky Warbler, Arctic Warbler, Willow Warbler and Wood Warbler (albeit the last two are in the Accidentals, Extinct Species section) are listed under Sylviidae. They should be Phylloscopidae.
