_Geographic range._--Breeds in Europe and Asia. Winters from Africa
east to Polynesia. In Micronesia: Mariana Islands--Guam, Saipan;
Palau Islands--Angaur, Peleliu, Koror, Babelthuap; Caroline
Islands--Ulithi, Truk, Lukunor.
_Specimens examined._--Total number, 12 (4 males, 7 females, 1
unsexed), as follows: Mariana Islands, USNM--Guam, 4 (July 16,
Sept. 20); AMNH--Saipan, 1 (July 27); Palau Islands, USNM--Peleliu,
3 (Sept. 9, 14).--Koror, 1 (Nov. 7); AMNH--exact locality not
given, 2 (Nov. 11, 19); Caroline Islands, USNM--Ulithi, 1 (Aug.
22).
_Weights._--The present author (1948:52) recorded the weight of one
male taken at Guam as 67 grams, and of two females as 57 and 63
grams. These were fall migrants taken by the NAMRU2 party.
_Remarks._--The Common Sandpiper has been known from Micronesia since
the time of Lesson. Tetens, Peters and Kubary obtained specimens in the
Palaus; the latter collector obtained the bird at Lukunor and probably
also at Truk. In recent years several collectors have taken the birds in
western Micronesia, where the species appears to be a regular visitor.
Field observations by the NAMRU2 party indicate that the birds are
usually found as singles and remain apart from other species of
migratory shorebirds which visit the islands. The margins of inland
ponds and beaches consisting of rocks and pebbles appear to be
preferred over the sandy, tidal flats. At Peleliu on September 9, 1945,
two birds were taken at a bare bank of coral at an inland pond. These
were the only two Common Sandpipers seen at the island. A specimen taken
by the NAMRU2 party at Ulithi on August 22 at a beach, piled with debris
from ships, has its entire and underparts stained by fuel oil.
