Record number of knot at Snettisham
Snettisham is famed for the bird life that flocks to its shores but this year is even more spectacular than usual.
A record number of knot have arrived on the mudflats owned by the RSPB for their winter roost all the way from Arctic Canada and Iceland.
There are estimated to be 140,000 of the bird thrilling visitors as they take part in huge murmurations over the seashore, flashing their pale underwings as they twist and turn.
This is a rare chance to see wading birds in spectacular winter migration formation.
The knots undertake one of the longest migrations of any animal from their Arctic breeding grounds to the coasts and estuaries of Europe, Africa and Australia, where they spend the winter feasting on invertebrates.
Wildlife photographer Les Bunyan, 64, a volunteer at the reserve, captured these wonderful pictures and told the BBC that it had been an experience of a lifetime.
"It's not just what you're looking at, it's also the sound you have to appreciate. When you get tens of thousands of birds flying around you – they make a lot of noise."
"I really do think this sort of thing should be on everybody's bucket list - just make the attempt to get out there and look at this type of thing."
The RSPB at Snettisham said that the knots are creating a great deal of interest.
Anyone wishing to see them should come around two hours before the biggest, highest tides for the best chance to see lots of waders moving between The Wash and the lagoons at RSPB Snettisham. Visit www.rspb.org.uk/snettisham for more information on dates and times.
RSPB Snettisham has a small car park which can hold around 80 cars. There are no toilet facilities on site.
The distance from the car park to the wader watch point is approximately 2.2km and includes steps up and over sea defence banks.
Covid-19 restrictions are in place for using the hides. Each hide has a set capacity and face coverings are required for those who are able to wear them.
Under no circumstance should visitors cross fence lines or climb shingle screening as this will cause disturbance to the internationally important wader roost.
If you chose to visit please respect all social distancing and hygiene precautions.
