The birds!

Yesterday I suddenly noticed a silence, it was quite uncanny, then I realised that the birds had gone! During the summer we have House Martins, usually until August, I think, but they have gone. The weather has been unseasonably cool and I suspect they have been conned into thinking it was time to go. Usually they sit on the electricity wires for a few days, planning the move but this time there was very little planning, just a sudden silence. I hope the latest broods were strong enough for the long journey!
