A little test - Canon 100-400mm or Nikon P6000?

The photos below were all taken at Alkborough Flats this morning - they are 2 male Stonechats, a group of Lapwing(can you spot the Ruff), a female Stonechat, Grey Wagtail(taken through a wire fence) and a Bullfinch. Double click on images for a better view and I would really be interested to know which kit you think took these pics.
