Blue tits

[Megan]

I put up my first bird house last month and a pair of blue tits are nesting in it. But they've been bringing moss and feathers and stuff like that into the box for weeks now. Could someone tell me how long it takes them to build their nest?

It takes them just a few days to build the nest but they will continue to bring bits it for much longer; it's like a repair job: patching things up, bringing in extra 'bedding' for the nestlings, etc.
