觀察細節
At the conservation area, a single crow flew in calling unmistakable cawing, landed in a small tree, took off and joined an identical non-calling bird about 200 yards distant; both flew to the north out of sight. Both birds noticeably smaller than CORA, and as can be seen in the photos below (of the closer bird), the bird is flying with steady rowing wingbeats, characteristic of crows, not ravens. The four photos were taken rapidly of the departing bird. That, together with the unmistakable cawing convinced the party of 5 birders that we were observing AMCR, not CORA.
