An afternoon at the Dhahran Expro Wader roost produced quite a good increase in wader numbers since my last visit. It looks like a few waders may be on the move as numbers of some species had increased significantly. Whilst at the site I took a few photographs of waders in flight, but as the light was not particularly good, due to the overcast nature of the afternoon, they are not as good as they could have been. I did manage to photograph Common Redshank that flew by calling as well as Ruff, Marsh Sandpiper, Kentish Plover, Dunlin and Little Stint. There were quite a few other species present but none flew close enough for me to add to the birds in flight list.
