| 説明 | American crows, or Corvus brachyrhynchos, gather on the roof of the University of Washington Bothell's Discovery Hall. Crows reliably gather in such groups around sunset, before moving to their communal roost in the nearby North Creek Wetlands. The video was captured with a motion-activated night-vision camera.Credit: Douglas Wacker/University of Washington Bothell |
