Seabirds create beautiful spectacle

Waders flock together seeking new feeding grounds during the incoming tide at the Royal Society for the Protection of Birds' (RSPB) Snettisham nature reserve in Snettisham, England, Sept. 9, 2013.

The reserve lies on the edge of "The Wash," one of the most important bird estuaries in the UK, supporting over 300,000 birds.

A few times every year, higher than average tides force thousands of waders including Knot, Oystercatchers, Sanderlings, Black and Bar Tailed Godwit and Plover to take flight and advance up the mud flats in search of food.

The event is one of the most incredible wildlife spectacles in the UK.
