Here is the coal tit back at Box2 again. In spite of what I said a couple of days ago, this is beginning to look serious!
She enters the box as though she owns it - and perhaps she thinks she does. I haven't seen much sign of the bluetits Lucy or Leo recently.
He (or should I say she?) stays in the box several minutes.
Apart from the brief glimps on 8th March I haven't seen this coal tit's partner though - and a partner is rather necessary for a successful brood of chicks!
