At Dengemarsh a superb male Hen Harrier flew through. A flock of 6 Corn Buntings and 10 Reed Buntings were near the Chicken Sheds. At the bottom of the Gully c20 Meadow Pipits and c30 Linnets.

 The 2 Black-throated Divers were still on the New Diggings along with a red head Goosander and 2 red head Smew.

Birders being moved on by the police for parking on the causeway!

The police seem to have a bit of purge on birders parking on the causeway at the moment. Though there seems to be a grey area around the legality of these actions.
I can understand being moved on between 07.30-09.00 and 16.30-17.30 when the wacky racers that work at the power station, are racing up and down the causeway seemingly ignored by the police.  After reading the following taken from the internet I am none the wiser.
 Parking on single white lines

If the road has a continuous single white line running along the left side, parking is considered legal but in some cases may be used to discourage parking - though this is subject to localised laws such as no parking enforcement signs or other such prohibited parking markings. 

However, in certain cases the single white line represents that there is no pavement , if this is the case then it would be illegal to park on a single white line. Such locations can often be areas where no street lighting is available and the continuous white line is 

used to define the edge of the carriageway.
