I'm not sure because I currently don't have my guide with me, but according to some photos I found, I saw that both had to wing bars, but in Sulphur breasted warblers, one is less prominent and almost invisible, whereas Goodson's has two obvious wing bars. Because of this, I'm guessing Goodson's, but I'm not a professional, I'm not really sure, can anyone else help?
