During the hot weather I have been doing work in the flat I'm building (out of the sun
![Wink ;)](https://forum.kitz.co.uk/Smileys/kitzemotes/wink.gif)
) , It was only when I noticed a pile leaves I realised I had company, It was a robin sitting on her nest a few inches to where I had been working for the past four days, It's a wonder with all the noise and dust I had been making it was not frightened away.
On the outside on the roof I have to finish bedding an end 'ridge tile' (thus sealing it of to the out side ) , But I have more birds nesting under the ridge.

I think it's a House Sparrow, I thought the young had gone but I have seen birds going under the ridge .
How long do they nest for. ?
How can I be sure when they have finished nesting. ?
