Hardcastle Crags, 19th May 2013

Wood warbler singing its head off (both song types) this afternoon, to the left of the main track to Gibson Mill, about 1/4 mile before.  Also a pair of grey wagtails catching beakfuls of mayflies near the mill.  The woods looked especially lovely today and why they aren't brimming with wood warblers (and pied flycatchers) is a mystery to me.  The habitat looks very similar to the Bolton Abbey woods.
