This is the third year we've had rooks nesting next door to us. Until today we thought they'd given up until all of a sudden we heard a racket. I said to Clare is that the rooks? And when she looked there were 3 pairs arguing over the nest.
By the time I got the camera sorted all the racket had calmed down with just one pair occasionally hassling the one's who'd claimed the nest. And then things calmed down further with a bit of preening and adding a stick to the nest.
Hopefully I'll get some footage of fledglings this year if they come before the tree is in full leaf.
Here's a little video...
