Ornithological information Population data are incomplete but numbers of wintering birds appear to be lower than in 1983 when the site was designated as a Special Protection Area. It is possible that very high numbers only occur in harsh winters, when several more species meet the A4i criterion, and the total number of waterbirds exceeds 20,000 individuals. Sterna hirundo and Sterna paradisaea, listed on Annex I of the EC Birds Directive, breed at the site.
Site description A shallow sea area with shoals, banks and islands surrounded by saltmarsh and agricultural land.
