Up till now I had only seen and heard Cuckoo's on my holiday to Rum, yes there were loads in Scotland. Lovely sighting yesterday on Barden Moor, by the lower reservoir.
Apparently the Cuckoo's that come to the East migrate over Malta, Sicily and up Italy where they are shot, West Coast cuckoo's come up through France and Spain and have a better chance of surviving. This has been shown by radio tracking birds.
