Latest WeBS report

In recent years, the UK’s estuaries and other wetlands have seen several notable changes in the birds using them. Little Egret and Avocet are now present in higher numbers than ever before, but familiar species such as Ringed Plover and Dunlin are at all-time lows, and other coastal waders such as Redshank, Curlew and Bar-tailed Godwit have also experienced recent declines.
The latest WeBS report, covering the winter of 2008/09, documents the expansion of four native waterbird populations in the UK, with Pink-footed Goose, Svalbard Barnacle Goose, Little Egret and Avocet all noted at record levels. Avocet for example has increased by over 1000% in the last twenty years.
In contrast, populations of six species reached an all-time low point; Mallard, Pochard, Goldeneye, Red-breasted Merganser, Ringed Plover and Dunlin – all of which have declined by at least 20% in the last twenty years.
