An immature Black-throated Diver was an unseasonal highlight, although this bird has been present for several weeks as a 'diver sp', finally coming close enough inshore to confirm the suspected identification. Also offshore 10 Common Scoter with nine Canada Geese SW and another three in off showing some seasonal movement. 

Several colour-ringed Oystercatcher were new in for another winter on the estuary where counts included 144 Redshank91 Sandwich and four Common Tern, 76 Whimbrel45 Dunlin35 Ringed Plover13 Greenshank11 Mediterranean Gull10 Sanderling, the six Eider, two Turnstone and two Bar and Black-tailed Godwit.

Elsewhere the bushes held good numbers of juvenile birds including Blackcap, Chiffchaff and Reed Warbler but two Willow Warbler were the only definite migrants.
