Numbers on Bodmin Moor seem fairly constant, I see them regularly in the course of my day job.I live off the moor with the valley wet willow woodland its here that numbers seem to have dipped that's why it's noteworthy hearing one this morning.For some reason the cuckoo always turns up really early at Emsworthy which is in the valley between Haytor & Hound Tor where all the bluebells grow.
