Recent Clematis flowerings

A couple of Clematis have started to flower, the one on the left is a dwarf variety growing up a metre high tower, the other more conventionally on a trellis against a wall. At present I am being entertained by a "flying school" of baby Blue Tits doing circuits around garden at high speed and attempting to land on spindly foliage which will not even take their weight.  A lot of enthusiastic squeaking going on. Two narrowly avoided flying into closed windows.They tire quite quickly then head for the shelter of the trees where the parents await.
