I got over to Colin's around 7am and we arrived at Minsemere around 90 minutes later, and probably timed it just right as a lot of cars were leaving so there were a few spaces in the car park. Unfortunately the bird had gone as well.
We were heading to the North Bank when Lee Evans said that the Swallows were over the Island Mere so we followed him, along with Dave Holman up the road to the high spot by the Springwatch building but unfortunately we were too late as the birds were last seen heading to either the Sluice or Sizewell, so we returned to the North Bank. Visibility had been rather poor with some drizzle and it was a bit cold but things did improve during the morning.
After about 15 minutes hanging around the Bank I and several others picked up some hirundines heading our way and the first one I got the bins onto was the Cliff Swallow, looking rather like a greyish House Martin with a red brown rump. It then spent a fair amount of time with the Swallows feeding at some distance over the field north of the old car park Sand Martin cliff and over the Dulwich Coast Guards building but was lost to view.
Colin and I decided to have a wander around the reserve for a while. The scrape was a bit dull-lots of Teal Gadwall Mallard and Shoveller, with a few Godwits and Dunlin. Five Bewicks Swans flew off as we got to the East Hide but were later seen on the levels and appeared to fly back. One or two Little Egrets were noted-someone had reported a Great White earlier I don't think it was seen by anyone else. Up to five Marsh Harriers were around as well-the only raptor seen on the reserve.
Sea watching was a bit pointless with the unfavourable winds with a few distant Gannets, one Common Scoter and a few loafing gulls around some fishing boats. A very nice bonus was the Purple Sandpiper on the Sluice groin.
At one point I had it in the scope perched in one of the small Hawthorns, and it could sometimes be followed in the scope while it was in the air. Getting it in the camera was a bit more of a challenge and my best images were obtained when it was more or less overhead, so lots of underside shots. When it was flying low, it seemed to keep it's distance and the few side/upper-side shots I got were rather poor. Still, it was nice to get such good views of a bird I never really expected to be able to see (rather like last years Crag Martin) in the UK.
