I was at the other office today, outside the window there is a tree and there is the remains of a crows nest.
I was sat at my desk and heard a Crow calling. I looked out and there was a Crow on the nest calling, he then flew off. A bit later he was back calling and then another flew in chased him from the nest to a nearby and branch. The new one sat on the nest and they crowed at each other.
I hope I may get to see some babies crows!
