Our story this morning starts with Carlos inside the box, perched on the exit hole, "flashing his white cheeks", as described in British Tits, to the world outside.
We've finally come to a decision about naming the pair of bluetits in Box1. We shall call the male Carlos which is an aristocratic version of Charles with a touch of Careless in it! The female, who is a pearl, we shall call Megan which is a variant of Margaret, Greek for pearl! A bit tortuous, but you have to have some reason for names!!
