After a brief search and a few stops to photograph the many singing Willow Warblers, we found 2 Adders basking. They hardly moved while I was photographing them, and I was able to get very close. A couple of Blackcaps were also singing there.
Ring Ouzels were the next target, and we had hardly pulled up in the car park at Harthope Valley before we heard one. A short trek up the valley produced 4 Ring Ouzels altogether: two males and two females. 3 Wheatears were also there as well as more Willow Warblers and plenty of Red Grouse.
