Utter concentration

There were a family of Blue Tits in the Crabbe Apple tree.
  I think the youngsters were getting food hunting lessons?  lol 
 They were hidden well out of the way and there wasn't a decent shot to be had of them!
  The adults were finding an amazing array of insect food for the young.
I would think there were about 6-8 young,so they have obviously had a good breeding season and will hopefully go on and have more!
