And so after a week of watching and waiting - and counting - we have a clearer picture emerging of what is going on with the little terns in east Norfolk. By the end of May, almost a month after they first started arriving on our shores, we have absolutely no birds at Winterton. This has been the preferred location for the past five years and has had two incredibly successful breeding seasons in 2012 and 2013 which between them saw over 750 little terns fledge. Now it appears that Winterton is out of favour. Every day we have walked up and down the beach alongside our fenced area and at most we have seen small groups of four or five terns flying overhead - but none landing. A boat trip to Scroby Sands on Friday 27 May - the first opportunity to visit this huge sand bank - was unfortunately cancelled. The breeding ground for many tern species including the little tern, it may have shed light on the whereabouts of our east Norfolk population. By week's end, however, we are relieved to see that a substantial number of little terns are seriously prospecting at Eccles, to the north of Winterton. This, of course, was the only east Norfolk site which fledged little terns in 2015. We have, we think, upwards of 150 adults with many of them courting and even beginning to 'scrape' in the fenced area. Nest building seems to have commenced in earnest. We might be in business.
