The shelducks are a group of larger often semi-terrestrial waterfowl, which can be seen as intermediate between geese (Anserinae) and ducks. They are mid-sized (some 50–60 cm) Old World waterfowl. Their diet consists of small shore animals (winkles, crabs etc.) as well as grasses and other plants.
COMMON SHELDUCK (Tadorna tadnorna)
This is a big, colourful duck, bigger than a mallard but smaller than a goose. Both sexes have a dark green head and neck, a chestnut belly stripe and a red bill.
RUDDY SHELDUCK (Tadnorna ferruginea)
The Ruddy Shelduck is a member of the duck, goose and swan family Anatidae and is classed as a Shelduck. In Western Europe the ruddy Shelduck is considered a pest as many captive birds have escaped and established themselves in the wild and are a threat to the native waterfowl due to their aggressive behaviour and interbreeding. Due to this the Ruddy Shelduck is subject to an eradication scheme
