Chaffinch or Hedge Sparrow?

Had a busy day with yoga first thing and then carried on with writing the Christmas cards.  It nearly kills my hand (arthritis?) but I love to receive them from friends and family so it's worth the pain of actually writing them. 

The light was fading when I realised I hadn't blipped so I quickly snapped some of the little birds coming for their last feed before nightfall.  I couldn't decide between the chaffinch or the little hedge sparrow for my main blip so put the little sparrow in as an extra.
