Slimbridge have recently released a video on Youtube about the new 'Waterscapes Aviary'. It is based on various British wetland habitats including estuary, ponds and lakes, reedbeds and wooded wetlands; it also has a diving duck tank.
Species mentioned or shown during the video include European spoonbill, little egret, smew, garganey, pied avocet, Eurasian oystercatcher, common redshank, ruff and a pair of common ringed plover. All the birds came from either other zoological collections or private aviculturists.
