crows

I have passed thru Fairfield and Skowhegan 3 times in the past weeks and have seen large flocks of crows in fields next to Rt 20. I'm sued to seeing 10-15 in a flock but these looked closer to 50 and up. A friend was in that area on I95 closer to Pittsfield the wknd before Thanksgiving and saw a huge flock flying by. she said the sky was black with crows
