There has been litterally hundreds of black birds flying over our house and feild for the last 30 minutes. The trees lining the river fill up then empty. Again and again. I have no idea where they're coming from or where they're going but it's very strange. They aren't loud like a murder of crows. In fact they made almost no sound at all.
I can't imagine that they're all migratory. Very strange indeed.
As quickly as they came, they disappeared again. The trees and the sky are empty.
