There appeared to be about 16 nests at the heronry this morning, though I'm not sure if all were active and I may have missed a few as I didn't linger long in order to minimise disturbance. Nearby, at Waun Garthenor NR a Willow Warbler was singing. I counted 12 Chiffchaffs on a 2 hour walk. Wintering Starlings have all departed.
