Cuckoos this spring

1 June - A Cuckoo calling at Blakehill this evening. They've been regular here this spring, for the first time for several years. It's been a good year for them also in the Water Park, with singing males being fairly numerous, and females also seen and heard bubbling. Let's hope that their decline has been reversed or at least halted. Interestingly, although the southern English population has been declining, they are increasing in Scotland. This must depend on several factors, including migration and wintering areas, host species populations and food supply.
