觀察細節

Heard only as they were flying by to the west of my yard. 1st one call fairly near ‘wheeer!’ with bit of quaver. Then more calls fainter as I got a recording going. I think three voices. I think moving N or NW. Faint on recording with calls at 6, 10, 12-13, 17 and 23 secs. Distinctive call I know well. Rare at Ken Caryl but pattern of occasional early fall recs.
