This doesn't look like a bluetit - or any other tit for that matter!
But what is it?
We had another visitor today - and this time it was much more interesting.
Ah! All is revealed - an inquisitive wren, perhaps looking for a useful roosting place
The observant among you may notice that the second picture was taken before the first! In fact Jenny visited the nest box several times this morning but only hopped in once. However, the best image of her looking in was taken later than the time she entered the nest.
We also had another visit to Box2 from our grey squirrel. I hope that it does not become a nuisance.
