Thurs 11th.
Sorry- a bit late. Scaup as skittish as ever by railway bridge, but otter performed on and off !
Looked like a much smaller female ? Worked downstream from 13:30 - 17:00 ending up well below boatyard and eventually in field ditch. Took several snoozes en route.
What a pleasure to meet Josh + Rachel.
Superb day and weather .
