Just sitting outside watching

We or should I say the birds now are resupplied so after topping up the various feeders I sat outside for a bit watching.  I thought that we only had a pair of Long-tailed tits visiting (but maybe they belong to the front garden), this afternoon I saw at leat three.  This was my best shot of these birds and my first for this winter.  What always amazes me is that they carry on feeding with little regard for me sitting there.
