An isolated Eurasian blue tit outside my window

I've noticed this lone blue tit sitting in the tree and flying in to feed on suet pellets outside the back door. I've watched it fly off with food onto these branches and then wait, for ages.

I fear it was a late offspring and that its family has moved on. We've had many tits breeding locally and it seemed to have been a successful year for them. In the current hot conditions the bird life has reduced in our garden.

I do like the way it is looking at me directly and seemingly unafraid of my presence. Even with a long lens I wasn't far away.
