Up! Always and forever, the Treecreeper goes up, up, upwards. Never down, hardly ever sideways, though often, in the process of going up, spiralling round and round a trunk, a branch, to the top. And then, flying quickly down to the bottom and heading upwards once again. Unusually, today, this little Treecreeper flew down to the very base of a huge Lime right in front of me and I followed it round and round the tree, until it was too high to see. What a treat!
