A good pied flycatcher site is at Barbondale, very close to Kirkby Lonsdale.

Cross the bridge then turn left and walk west along bridleway. On your left is a mix of alder carr and oak that is good for pied flys and redstart. On the right is more open fellside with scattered scrub, this is good for ring ouzel and cuckoo. You will eventually hit a gate into the estate forestry, well former forestry Google shows conifers but they have been clear felled and broadleaves replanted. You can carry on along the bridleway through with woodland, the bluebells have been great but might be over by now, there are lots more usual woodland birds but not what you are after. Turn round when you want and head back the same way.
