This was my lovely Ash tree in January. The birds loved it almost as much as I do. The larger birds like crows would sit at the top, jackdaws would sit slightly lower down and the smaller birds like sparrows and chaffinch and members of the tit family would perch on the lower branches. I hung bird feeders on the lower branches and would have a constant stream of avarian visitors throughout the day.
And the sparrows are still nesting in the ivy.
