I have complained that it is often difficult to tell one bluetit from another, but here is one that looks different. He looks a male to me.
Now he's in the box, you can probably see better what I mean. His head feathers look scruffy and are streaked with white. Or is it just that it's been raining and he's got very wet!
That may be part of it, but I don't believe the differences are all down to the rain.
How different this bird looks. But perhaps this one has kept its feathers dry! It still looks quite masculine with its white head band being fairly broad and the head feathers being relatively dark.
They are clearly not friends though!
Looking and listening I think.
There's no let up by the bluetit inside!
A diplomatic retreat looks as though it has brought a cease fire.
No - that was wishful thinking. Look at the inside bluetit's beak.
"Clear off - this is mine!" he seems to be saying.
Perhaps we will have another fight on our hands before long!
