The small crab apples cling to the tree. The leaves have fallen. On a rainy day the birds swoop down to feast on the fruit. This is a great source of food through the winter. Sometimes some of the fruit lasts until spring at which point it has started to ferment. I can remember in my childhood, seeing birds flying erratically after they had feasted on some. I don't think there was permanent damage - it was amusing to see these drunken fowl.
