Susan,
We see it with regularity along the SC coast. Roosts of 40,000+ Fish
Crows are a nightly occurrence in the ACE Basin - we have had them on the
ACE Basin CBC roosting on a wooded island near the Bear Island bridge and
other field parties have had them on the Edisto River side of Bear Island
WMA. And Rat Island near Charleston Harbor used to have 5-figure Fish
Crow roosts regularly (before a tree die-off). Plus other examples.
This time of year long "flows" of Fish Crows can often be observed at dusk
flying down the Ashley and Cooper Rivers towards Charleston Harbor. And
flying down the Santee River heading towards the Delta. I have also seen
them flying down the Savannah River at dusk.
These roost sites move around and are ephemeral - presumably due to
disturbance, predator activity, etc.
