Sparrow or Dunnock?


I’m quite new to bird feeding but I have lots of different birds visiting and even a  Sparrowhawk which has had a few Starlings. 
I assumed the bird in the video above was a sparrow but now I’ve looked into it could it be a dunnock. The beak looks more like a dunnock. There is a few and they sit on the edge of my conifers popping out into the garden for food but always near the conifers. Aren’t sparrows more bold than this? I did see it chasing off  a coal tit though!
