Sorry for the late email, personal issues last night.
There were 10 !!! Black Vultures at 8:15ish at the pig farm on Division Road in Westport (on the Westport side). Also present was 2 Common Ravens, a Bluebird, 4000 starlings which must have attracted the 2 Cooper's Hawk.
The vultures appeared to be coming off of roost as they started quite low and then rose eventually out of sight (most of them).
