These lush weeds grow in a corner of the cold frame. As I draw, there’s a confrontation between two pairs of magpies with a lot of irate clacking. They meet on our chimney and two of the rivals lock feet together and roll down the roof tiles. The dispute moves on to the next door neighbour’s roof and, as I pack in, 
I can see them in the top of one of the ash trees in the wood, joined by at least two more magpies and a carrion crow who seems to be just an onlooker.
