The Cuckoos are on their way here. In the next few days someone in the valley should hear their first call. They need a steady southerly wind to ease the trip and the current south-easterlies are probably not quite enough. Some idea of their journey can be gauged by following this link to the British Trust for Ornithology’s satellite tracking of Norfolk Cuckoos http: //www.bto.org/science/migration/tracking-studies/cuckoo-tracking It will be interesting to see how they and the start of the local calls coincide.
