Huge flocks of waders, mainly Knots, over the Wash at sunrise: a wildlife spectacle. The Wash is one of the largest estuaries in the United Kingdom. At low tide a big part of the Wash turns into mud, at high tide the rising water pushes thousands of feeding waders to shore. The photos were made during visits in 2016 and 2008 in the RSPB Snettisham nature reserve. Music: Ryhlo tazibe by Kalio Gayo
