观察细节
As of 2019, with publication of Peterson Field Guide to Bird Sounds of Western North America, Pieplow is on record that RB and OB are distinguishable, on basis of form of first note. See pages 374 and 375. For OB it is a faint monotone burr, as seen here. That identification agrees with the expected subspecies group on the basis of range.
