At first light there were two ravens in the rookery, they had presumably roosted. Then at around 08:30 or so, first just two, and then eighteen flew through, heading west to feed. The main body arrived perhaps some twenty minutes or so later and checked in to the rookery before heading out west too.
In the late afternoon there were about 200 or so rooks present until dark. When I took the dog out late on, 23:00, I couldn’t hear any rooks and there was not a murmur although I shone the torch on the trees. However, a last look out an hour later and a few called. This is the first time rooks have roosted here since the autumn.
