Conditions: mostly cloudy, wind 15MPH, gusts 31MPH, 40F, wind chill 32F: sunset time 4:16PM
While passing through the area, made a short stop to observe the nightly roost, around 9:15PM, and almost 5 hours after time of sunset. Observed well over 6,000 Crows in tight roosting formation in trees along the north shore of Merrimack River immediately adjacent to the Rt. 495 overpass in Lawrence, on the east side of the bridge. Hardly any vocalizations and little movement. Lots of traffic noise and activity in the background with a good amount of ambient light from nearby highway light poles. Night vision optics were essential for observations! Both photos from south side of Merrimack River looking north.
