Continuing individual I first spotted on July 1st. This time equipped with a camera. Another audio recorded and appears to be singing at least the first two phrases of the 3-part song. Once again responded to a COFL but ignored PSFL. Spectrogram to uploaded soon to confirm. Post-observation details: After seeing the spectrogram, it appears it's the other way around for this individual and is the "more common" species of the complex. In the spectrogram at times 0:10, 0:19, 0:25, the individual makes a position note call which looks almost like an allopatric PSFL, or one that breeds near the coast, outside of the hybrid contact zone. On a spectrogram it appears as a wavy whistle that has a low starting point and high ending point. The other PSFL I've recorded in the county are a little more "intermediate" and the position note is kind of squished, making a "kink". That means one of two things, that I'm either really bad at distinguishing the two species by ear or a reiteration that spectrogram is best. And that also means the one I heard on July 1st and initially identified as COFL based on the overslurred calls, is probably this same individual and a PSFL. I'll have more details on that in that checklist.
