Conditions: overcast skies, wind SW at 5MPH, temp 39F; sunset time 4:34PM
Two of us out on Crow Patrol just after 4 PM starting with this stops at multiple nearby staging locations. As part of ongoing citizen science efforts, we continue to monitor as many staging locations, especially the early ones. The biggest staging area was observed about 1/2 mile SE of the general overnight roost area. This image was captured about 11 minutes after sunset time!
Next stop was the top of the McGovern parking garage with excellent views to the S/SW/W/NW. Significant numbers of incoming flight streams converging on to the rooftop of the B&D warehouse complex starting around 15 minutes after sunset time.
Again, we are seeing huge numbers participate in group swirling flight patterns in this area, prior to landing on roof area. At 30 minutes past sunset time, the Crows began a major final flight shift from the far end of the B&D roof top to the overnight roost. Large numbers were later seen within the National Grid substation, on the ground, wires, back trees, and rooftop areas. Even more were seen in the truck depot area, on the ground and perched in trees at rear of depot lot. This image below was captured about 20 minutes after sunset time!
