A specimen is reported by Vierthaler from the Blue Nile, but it seems a very uncertain record. There seems, however, no reason why the Dotterel should not occur in the country in winter.

There are two other Plovers as yet unrecorded from the Sudan which might be expected to occur, One, the Golden Plover, Pluvialis apricarius Linn., has been found as far south as Somaliland and Aden, and the other, the western race of the Mongolian Sand-Dotterel, Charadrius (Cirrepidesmus) mongolus atrifrons Wagl., has been recorded from the Red Sea coast to the south of our limits.
