I’ve located and visually verified two different Chestnut-sided Warblers this spring that were not singing the ‘normal’ song we know and love. Close but off enough that I was going through Magnolia, Redstart, and Yellow-rump thoughts before seeing the Chestnut face and/ or sides.
Good stuff on your analysis and spectrograms! ChrisP Yesterday we heard Bay-breasteds and Cape Mays also doing lots of variations. The Chestnut-sided I heard did not seem to sing the regular "Pleased Pleased to meet you", which we hear in Ithaca area, but instead they had totally a different dialect. I also found all three species singing at the same time and there was overlap of songs. So how do they recognize each other or different species when they are all singing together in same band width.
