Late evening walk along river Waveny on Oulton Marshes. Only about a mile from sunset to darkness. Plenty of dragonflies with the best being  Broad Bodied Chaser. We also watched for some ten minuets a pair of HOBBY'S hunting low over the reed bed on far side of river. We also picked out the call of a TAWNY OWL from the far side to and a LITTLE OWL on far west of marsh. The call of a BARN OWL also from Fisher Row.
