Very quiet at this time of year, best likely to be flocks of Siskin and Redpoll, and winter thrushes.
Good in late spring / early summer, for Whinchat, Wheatear, Redstart; maybe still Tree Pipit, but they've crashed in the Cheviots in the last 2 or 3 years. Further up the valley, Ring Ouzel, though they're easier in the Harthope Valley.
Some raptors if you're lucky, but fewer than there used to be - not surprising given the increase in grouse moor management.
