Seriously, stone them.
Apparently the sudden cold has shocked the crows into a fighting frenzy to keep warm. Tonight they're gathering in the trees around my apartment and cawing ... and flying around at each other to keep warm.
It's snowing a very light flurry of crow feathers.
It's kind of eerie to hear the sound of wind and then realize it's just crows ... that many of them ... flying around outside my apartment.
I'd take a picture, but it's dark, and they're dark, and it's cold.
Not much sounds creepier at night than a huge flock of crying crows.
