Detalles de la observación

First two recorded at different location than third one. First two: Merlin was convinced this is Bay-breasted, but checked with Larry / Mary / Aaron / Greg who are pretty sure it's Blackburnian, without final note. Third one: Sounded a lot like bay breasted (Merlin was marking song as both bay-breasted / blackburnian), but got looks which confirmed ID as Blackburnian. In the spectrogram, notice the increase in frequency in the last note of the song, right up to 9.5-10 KHz. That's not there is the bay-breasted, but IDK if that's distinctive. Also the first part of the notes look flat rather than descending (like in bay-breasted). Note that I've removed parts of audio with too much background noise, so the time period between two different songs could be meaningless.
