Waltham Brooks

Grazing marsh with a large open water area important for birds.

Almost opposite our Amberley Wildbrooks nature reserve, just across the river, lies the grazing marsh of Waltham Brooks. In winters of very heavy rainfall almost the entire reserve becomes a giant lake. Fortunately the river banks of the Arun floodplain have been built up for flood defence creating a good elevated walk-way to view the reserve from. Wildfowl such as Teal, Shoveler, Wigeon and Pintail take advantage of the sanctuary and the feeding opportunities the flood waters offer. In summer the lake can almost dry out leaving muddy margins important for breed­ing waders such as Lapwing and Redshank and the occasional passage migrant such as Green and Wood Sandpiper.

Dip into the world of dabbling ducks

Ducks can be split into two broad groups: dabblers and divers. As the name suggests, diving ducks feed mainly by diving underwater, using their strong feet (and sometimes their wings) to swim. Dabbling ducks, however, feed predominantly at the surface, sometimes even grazing on land. Many dabblers can often be seen upending, with their heads underwater and their bums in the air.
