Sorely missed

These last few weeks I've been revisiting a tetrad that I surveyed for the National Atlas above Llanfair Clydogau in the Clywedog valley. It was probably about 5 years ago that I walked this area last. Present before but apparently now absent were; Curlew, Cuckoo and Spotted Flycatcher, 3 species that are commonly said to be in decline.
