The second time was on Saturday. Once again I was alerted to the presence of the bird by its call, which I followed through the field. After much jumping over brambles and being stung by nettles, I caught up with the Cuckoo which was darting about between the shrubs.
The zoom on my camera enabled me to get some clear shots from a distance, but when I tried to get closer it spotted me and flew off. Even as I type I can hear the bird calling outside, so I think I'll set up my hide in the field later and see if I can get some close ups of this increasingly rare animal!
