观察细节
Call and spectrogram consistent with PAWR over WIWR (lacking SOSP like sound and not stacked 'parabola' shape of WIWR call. Overall a drier, sharper call). Not overly dull, but throat color even in bright light does not contrast sharply with breast/neck, and in neutral light (3rd photo) bird has more rich-colored appearance with consistent throat color. No white-flecking to neck sides, hardly any white on wing coverts, but unclear how diagnostic these plumage traits are.
