觀察細節
1x1 count of migrating birds under ideal conditions; all adults; unlike kestrels, at least 2/3 were heading W or WSW into the wind, possibly correcting after having been displaced too far E and getting nervous about heading towards urban Boston so close to the coast on westerly winds? Record count for me here.
