Following the sparrowhawk thread - I had a lovely encounter with a goldcrest yesterday. I see them fossicking in the undergrowth now and again, but this was ay head height in an apple tree, picking off insects, less than 1m from me. I had a lovely view. So tiny! Not much larger than a walnut. I was watching him for several minutes, till he moved into a further tree.
When I came back that way, no sign of the goldcrest, but there was a robin, who looked HUGE by comparison.
