Cuckoo calling

On Sunday 15th May, there were 2 Green Hairstreak garden on the Wisteria in particularly sunny weather. At Kessingland I watched a Cuckoo fly calling from the caravan park over to the sewage works marsh and I sneaked up to it when it was perched on a dead area of branch, only for it to fly just as I was focusing on it with the camera very frustrating! A Holly Blue butterfly was seen here too. The Cuckoo was seen flying south from the sewage works and very good views were seen in flight when it appeared to fly back towards the caravan park area.
