A wren, I think. A couple of years ago I put an open fronted nest box on the back of the shed, it’s about head height (it’s a small shed) and round by the water butt. Not, on reflection, the best location - it could easily have been higher and beyond the butt. Anyway, we’d noticed a nest had been built in it this year, but hadn’t seen any occupants. Until today, when I went to the compost with my failed pizza dough (the dried yeast turned out to be 6 years beyond its best before date….) and decided to have a look. And a small brown job shit out if the box about a foot in front of my face! Too small for a robin or a sparrow I think, so probably a wren. Cool. All we need now are blue tits in the other box - they missed last year.
And, whilst we do see wrens in the garden, today an altogether rarer visitor, a song thrush on our lawn, which is unusual as it’s not the wide open spaces they prefer.
