观察细节
Flyover. Called repeatedly overhead for about 20 seconds, unmistakable rolling/rattling-like "prrrrit" calls, interspersed with "piuu" calls. I have extensive experience with this species and its calls, with no possibility of confusion with any other species. Recording of one "piuu" call with the phone is available and will be uploaded. Unfortunately an airplane started passing when I managed to turn on the phone to record, and couldn't get any other calls on tape. I am aware that this species has a scarce occurence in the region.
