While heading home from the hospital tonight, minutes before sunset time, under overcast skies, light wind from the NE, and temp at 45F, and sadly, no time to spend on Crow Patrol;  looked to the SW and spotted a few Crows.  Over 50 were seen perched all over two antennas atop the Valebrook Apartment complex on Summer St. in Lawrence.  Was able to take a moment and snap a long distance photo of this small squadron.  They likely made their way over to the overnight roost by the New Balance building along the Merrimack River!
