After exhausting day at work, certain I'd need a short nap once home, I was greeted in parking lot (Watertown near the Arsenal Mall) by sound of FISH CROWS!
Found 2 in the parking lot below, one foraging, the other squawking, and they joined two more up on building roof. Proceeded to Blair Pond, 2 days after last visit and had great 30 minutes
