We all saw an enormous dark-coloured bird high in the sky being harassed by two crows (average length about 45 cms and wingspan about 100 cms) who were obviously much smaller. It most definitely was not a Turkey Vulture. The only other option is a Golden Eagle (average length about 76 cms and wingspan about 200 cms) winging its way south.
Unfortunately those of us with cameras were unable to photograph the bird in the few seconds in which it appeared.
Here are images from various on-line sites:
Golden Eagles are rare but widespread in open country relatively far from people, especially mountainous areas.

This morning’s group:
Ruffling the colors of the forest leaves,
The winds make music as they come and go. – John Critchley Prince (1808–66)
