Flat calm conditions all morning is a bit odd here. 1,163 Cormorant went out fishing early on plus 530 more in from the north to the fishing grounds later on. Offshore southbound 295 Red-throated Diver & 2 Shelduck with northbound 7 Brent. Another Shelduck was siting on the river. Whilst scanning through the gulls in the harbour behind us a Black-necked Grebe was noticed fishing by the confluence of the Orwell & Stour about 3 miles up the Haven roughly straight out from where the old Dooley terminal is looking towards Harwich if one was in the docks. It was present for several hours and may well have only been seen as a result of the low tide in the "mill pond" like conditions having presumably drifted down one of the two river systems.
