Blue tit activity

More activity this morning
A lot of fanning in the box, more preening and feathers
Fingers crossed

I’m in a bit of a quandary,I need to go cut the grass, but I’ve got her in and out of the box, and it definitely looks like nest building has started?

What do you adivise?

Grass cut, birds were still active

Thanks Alan, I’m sat with a cuppa watching them now
Oddly I have two boxes about a metre apart and birds in and out of both
Both quite fat now

Here they are, camera is in the one on the left

Just one in each box Alan
The camera box is more active

Another odd observation, the same bird is visiting both boxes, albeit on more than the other.
Watched collect grass and foliage from under one of our bushes.
Definitely keener on the camera box
