觀察細節
Minimum count by twos. All in reach 4 or farther downstream, in a loose, dynamic flock. Early in the morning, at least 6 flushed from the field between the transect start point and the creek in reach 4, where there were notable numbers of grasshoppers - I suspected the magpies were feeding on these. Some presumed hatch-year birds seen (with stubby tails) - did not attempt to estimate proportions.
