觀察細節
Minimum exact count. Groups seen in flight several times, crossing the stream course above the diversion dam. Pale underneath with mostly black tail, making high-pitched "seep" or "see-bit" calls. After I watched one group of approx. 4 fly S or SW overhead, I counted 29 more birds (very distant) to the north in flight, going farther north, and heard similar calls from their vicinity - perhaps all HOLA?
