P.S.to the previous

Just after writing the previous ... literally just after -
I went outside and there by the back door was this little thing...... a perfect tiny bird nest.

Birds nest showing good use of local materials

Looking closely I could see strands of baler twine..... there's a lot of that around here ..... and, lining the inside, what is obviously pig's wool.
Clever bird.
If there's one, there must be more.......................
