Dettagli dell'osservazione
I saw at least this many, all at one time, together in a big swirling kettle overhead. Total number of birds in the kettle was actually greater, but a few Red-tailed Hawks and at least one Peregrine Falcon were also part of the formation. There were almost definitely more ravens around than this, but some kept going out of sight, either flying downslope or perching in the trees. Large black corvids, as large as the Red-tails and much larger than the Peregrine both of which interacted with ravens several times. Had elongated wings, massive bills, tails that bulged outward in the middle, and deep, resonant, croaky voices. Not the first time that I've observed over 20 ravens at one time from this location.
