Detalhes da observação
FOY. Thought I might have missed my chance to encounter one this year. Singing and calling on both sides of the road. Never did see it but recorded both calls and song. The first spectrogram is of a call. The rest are of the territorial "song." Note the slight hooks on the notes in the last four spectrograms. The last spectrogram also shows a second line at a higher frequency on each note (especially in the middle of the recording).
