Great Spotted Cuckoo

This morning at 10.30 I heard the calling of a Great Spotted Cuckoo.  I thought I had mis-heard at first because I didn´t think they would be about so soon in the year, but a few minutes after hearing the call I saw a cuckoo being chased away by a magpie.  All the local magpies are now on full alert, and will have to be vigilant for a while to come if they want to avoid being foster parents to cuckoos.  Let´s hope the cuckoos are successful!
