觀察細節
All four heard and seen simultaneously, first in the the usual area in the woods between the Entomology complex and composting facility and then high in the air. From the woods near the Entomology complex, I saw as many as three simultaneously flying and perching within the wooded area while at least another could be heard croaking nearby. (Attached recording taken of several birds within the woods.) Very large, fully black corvids with heavy bill and long head, long club-shaped tails and long wings. The birds soon flew up out of the woods and began circling over the trees, eventually soaring to extreme altitude in a matter of a couple minutes (nearly indistinguishable dark specks to the naked eye). Binocular view (observed with Andrew Peel) revealed four Ravens (same features noted as described before) soaring in circles with a loosely associating Black Vulture and many swallows that appeared to be even higher.
