_Remarks._--Stickney (1943:8, 9) summarizes the available information
concerning the Sanderling in Oceania. The bird may be classed as a
regular visitor in eastern Micronesia; the most western record is from
Ulithi in the western Carolines. It has been recorded also at Guam and
Jaluit.
The NAMRU2 party secured one Sanderling from a flock of approximately
thirty birds containing this species and _Charadrius mongolus stegmanni_
at Pau Island, Ulithi Atoll, on August 21, 1945.
