It was not as cold this morning as it has been previously: there was no frost on the grass! There were thin clouds in the sky, and a definite haze. I don't know if that was due to the Icelandic volcano's ashes, not having a huge amount of knowledge of clouds ...
Certainly the birds were not affected.
We left the house at 6.40 a.m. and did the usual round. This morning, a single raven flew to the ground as we came into the ravens field.
