Walking home from the store yesterday I heard what sounded like a raven
and was startled to see two crows flying circles around each other just above
the treetops. They were clearly crows - squared-off tail, trim appearance, not big.
As I continued on, they flew above me, making two completely different
vocalizations that were also very raven-like. I've never heard this before
Are crows known to imitate ravens?
