Stone Curlew at Alkborough Flats?

Well I'm just back from a stint down on the flats in search of the Stone Curlew but alas to no avail.  Alkborough is a large site and it does seem like looking for a needle in a hay stack.  When Wayne saw it last night he saw it in flight, flying over one of the fields set with broad beans, it continued passed him and appeared to land a fair distance away on the foreshore where there is no public access and he was unable to relocate it - who knows where it will be now!
