After a tip off from Dick at 14.47 that Cliff Dell had a Diver species on the north lake , I dashed over from Tilbrook and at 15:00 was stood next to Cliff watching a fantastic GREAT NORTHERN DIVER at c 30 yds range - Ben Miller and Dick joining us shortly afterwards (the former fortuitously driving along the M1 on his way home); it is in the North Eastern Arm ranging from that bay to the other side (south) of the island , it is diving frequently, often spending a minute under the water only to surface a distance away , stay up for 10 seconds and dive again , it appears to be a juvenile. Ben Miller is onsite and obtaining images.
The best place to view is from the boardwalk along the edge of Redcote Manor ( Road ) which is actually in the Walton Park area of Caldecotte http://maps.google.co.uk/maps?q=caldecotte&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&hq=&hnear=0x487654ab27e3728b:0xdc89dd69b75a8705,Caldecotte,+Milton+Keynes&gl=uk&ei=ItnDTpzxMMPJswbCkrz2Cw&sa=X&oi=geocode_result&ct=image&resnum=2&ved=0CCcQ8gEwAQand
zoom in under the area of Walton Park It is the 17th record for Bucks following birds in 2006 and 2009 at Calvert. Great find by Cliff in a woefully under watched area of Caldecotte lake hopefully it will still be there in the morning ! (Simon Nichols)
