SNETTISHAM, UNITED KINGDOM - OCTOBER 12: Knot and Oystercatcher feed during the incoming tide at the RSPB's Snettisham Nature Reserve, on October 12, 2010 in Snettisham, United Kingdom. The reserve lies on the edge of 'The Wash', one of the most important bird estury's in the UK supporting over 300,00 birds. High tides force thousands of Geese and other waders including Knot, Oystercatchers, Avocet and Grey Plover to take flight, and advance up the mud flats in search of food.
