觀察細節
I was surprised to hear one in the pre-dawn chorus on this early date, especially given how far behind migration is this year. A diagnostic portion of song can be heard periodically in the recording. Also of note, the bird is precisely where multiple birds have been detected on previous visits, i.e. they breed here.
