In reply to dr_botnik:
You are normally allowed to climb on the Right Wing but not the Carnage Area as the birds normally nest on the Carnage belay ledges.
Routes likely to be climbable include Pikedaw Wall, Junkyard Angel and Kirkby Wall all 3* classic HVS's and Wombat the classic E2.
If the birds have nested in a different area there will be notices up at the start of the track and nearer to the crag.
