The box has quite a lot of poo from last year's nest on the floor. Mrs. B. is clearing it out, but she also seems to be just chucking a lot of it around. A technique I have yet to try myself, when cleaning the house.

Mrs. B brings in some nesting material and chucks it on the floor before doing that flapping thing.

Mrs. B practices the flapping she'll be doing when making the nest. The technique involves bringing in some stuff and then flapping to spread it around.

Mr. B. does a typical bloke's attempt at cleaning - picking up a couple of bits of dirt before getting bored and leaving.

Mrs. B. comes and has a look at the mess on the floor, before hopping up to the door and giving it a damn good pecking. This is quite common with blue tits, and no-one really knows why they do it.

Crow attack! Listen to the crow/jackdaw scrabbling around on the box. Look to the left of the screen and you can see a long pointy beak coming in. The blue tits avoided the nest for a week after this - maybe it put them off?

The first recorded visits of the year. Just a quick hop in and out to get a feel for the place. They will keep coming in with increasing regularity until the nest building starts, and it's all systems go!
