Just worth noting that the cold weather has brought on some new behaviour from the grey partridges. The cock birds are suddenly being very vocal and restless with each other, and I saw one of them keenly rogering another this morning. Perhaps this is in anticipation for spring, and I daresay this recent cold is the only thing that has given them any indication of changing seasons. Their restlessness is stirring up the blackcock, and there is quite a hormonal little gathering starting to brew in the front garden. I will have to have a look in my GWCT manual to find out what my next move should be.
