Tis the time of year for the Crow Roost Spectacular in Renton, WA. Hope you enjoy them streaming thru the trees by our office as they head towards their evening party. This is so amazing over the years I have not gotten tired of their annual roost behavior. The din of their voices and as one coworker told me… you can hear the crow poop falling all around you and our cars.
Crows of Arroyos 
Wow there are so many of them! Cool video.
it is a spectacle for sure.. and I tried many times to get that movement so it gave you the feel of many in flight… patience is so worth it… Thanx for the kind words r
