The above is not very clear, but, believe me, this is a Redstart's nest right up under the eaves of our barn, where the men are hammering the laths into place; it has about 4 or 5 fledglings inside. The mother bird returns each lunchtime and evening to feed them. With all the noise and human activity going on, I'm amazed that she hasn't abandoned them.
It'll all be finished soon, so in a couple of days time they'll be back underneath the tiles again, and she'll have her peace returned.
This is what it looks like up there. I braved the ascent whilst the men were at lunch.
The other side is finished, and on this side it just requires a couple of Velux windows to be fitted, the tiles to be put in place, and the guttering fixed.
The men have been very efficient; it's only been a week so far. They've continued to work hard both in the rain and the heat of the sun.
They should be gone by Wednesday.
