Whilst birding the Jubail area recently I saw a lot of Dunlin with some still in partial summer plumage. The subspecies we get probably include alpina and centralis (if valid and not included in alpina) that breeds in north-east Siberia from Taymyr Peninsula to Kolyma Delta and winters from the eastern Mediterranean and Red Sea eastwards to southern Asia. Dunlin is a very common passage migrant and common winter visitor. Although I see Dunlin most visits, in the autumn this visit provided more birds than normal with quite a few different birds shown below.
