Here in Greensboro we have an annual winter crow roost, usually on the west
side of town, although there is usually a smaller one downtown. You can see
groups of crows streaming to the west at dusk, and judging by the calls
heard they are a mix of American Crow and Fish Crow, mostly Fish Crow.
This year I found the roost in the area of an I-40 exit near Costco. My
guess is a couple of thousand birds - every tree in sight was full of them
and they were lined up along the top of buildings.
The downtown roost tends to be smaller - hundreds rather than thousands -
and has only been gathering for the last 10 years or so, in trees lining
the main streets. They have caused an outcry among business owners
downtown, who complain to the City about the large amount of bird droppings
left on the sidewalk and worry that their customers will get pooped on when
coming and going from their business.
