觀察細節
Two birds heard first, then seen soaring (without binoculars, but unique wing shape of the lower bird was quite visible. Upper bird circling with tail closed, tail looked brigther then the rest of the underparts against sunlight). Possibly a third one higher up. Recorded calls. They were circling and soaring, then headed SE toward Terán
