Sandwich Terns

Another day, another site and another good county bird.  This time 13 Sandwich Terns that were found by Mike Mayall at 09:30.  I managed to get there fairly quickly and the birds were nowhere to be seen.  However a minute or so later I heard a Sandwich Tern call and they all landed on the sand spit.  They remained there until after 12 noon at least  (still present as I write this as far as I know).
Three of the birds had been ringed, one with colour rings Red over Blue on it's left leg.  It is possible that these are Scottish birds.  Details awaited.
My initial thought that this flock could be a county record but that is in fact a flock of 26 or 27 flying over Wavendon in April 1989 and another flock of 13 at Willen Lake MK on 22nd August 1987.  Interesting that the Willen date is close to todays date.
Thanks to Mike for getting the news out quickly.
