Detalhes da observação

Rare in CT. One called among the rest, which I presume to be type 12. Lower choowp-choowp call that is entirely descending. Call notes below 4.5kHz and over 0.04 sec. I think the spectrogram fits the 'kinked' (down-up-down) call variation of this type, which apparently is rarer for the East as the 'unkinked' (entirely descending) variation is the more commonly encountered.
