Eurasian bittern
Many wild birds which have now made their home in the Centre cannot be found anywhere else in London, and there are nationally significant numbers of gadwall and northern shoveler. Other wild birds include Eurasian bittern, northern pintail, northern lapwing, water rail, ring-necked parakeet, Eurasian sparrowhawk, sand martin, common kingfisher, little grebe and great crested grebe. The centre also holds a collection of captive wildfowl.
