Ok I'm guessing it's dad, no woman would appear in public in such a mess!!!
However, he seems to have managed to rear about 5 youngsters, as they all arrived at the same time.
I was actually beginning to despair of seeing any as the weather had been so cold and wet it seemed the majority of Blue Tit nests had failed this year, so you can imagine my delight at seeing them.
Then a couple of weeks later I realised there were about 10 youngsters, very difficult to count them, as they move around so quickly.
