Observation details
NFC 1. Nice! Just like evan's o'brien description: "A long, high, "szeeee". Typically slightly rising and sometimes with a faint sibilance." Double banded around 8khz. Flight call occurs a little after 1 second into the recording. I have recorded this species before at this location: https://ebird.org/checklist/S150892280. Duration of this call looks just fine looking at this compared to my previous example and the evan's obrien literature.
