Anyone know what it means if rooks don’t sleep in their rookery
We have a rookery near our house. That is a small area of trees were rooks nest. For years and years and years the rooks have roosted in the trees. What a noise they make and what a nuisance they can be when I put the bird food out
When dusk was coming in I saw this flock of rooks flying away from these trees. They flew over the fields. I watched them until the disappeared in the distance.
Why did they do this?
