This picture show a drake Northern shoveler using its unusually shaped beak to search for food. The broad beak is edged with lamellae, which act like sieves trapping the small aquatic insects on which these ducks feed. Several birds can sometimes be seen swimming in circles stirring up the water so they can all feed.
A few pairs nest in Britain but several thousand migrate here for the winter. Birds bred at the nature centre have been sent to other collections, including the Wildfowl and Wetlands Trust.
