Oooh! These look good.
He/she looks as if they are saying thankyou in this pic. The photos are of two different birds - the male and the female - though I can't tell which is which and their babies are just a few feet away in this open fronted box on the garden wall.
It's hard to believe that a couple of years ago nothing would grow in this corner. It was dark, dank and horrible. Then our neighbours had about 10ft cut off the top of their ghastly conifer hedge and let sunlight in once more - what a difference. I have just planted a few more cowslips in the empty space round that square stone in front of the bench - they were selling them off at the garden centre.
