Interesting variability in pied flycatcher laying dates this year. Birds definitely started laying earlier. Some nests at Cwm Cletwr are 7-10 days ahead of last year (chicks at stage in-pin stage today). Those in the Rheidol valley appear to be a few days earlier too. It's been a poor year so far for blue tits on the Rheidol too with many nests already failed or abandoned."
