One of the most spectacular wildlife events in the UK takes place in north Norfolk, when thousands of migratory birds arrive from Arctic Canada and Iceland for their winter roost.
To witness the balletic flight of the knot requires specific weather and tide conditions, making it a rare treat.
"There are possibly just three or four mornings a year when they'll do this," said wildlife presenter Chris Packham.
The RSPB Snettisham reserve recommend the following days to watch the wader spectacular at the start of 2010.
4 Jan at 7.15 am, 2 Feb and 1 Apr at 6.40 am, 2 Mar at 5.45 am, 3 Mar at 6.15 am. For more information call 01485 210779.
