Part 45

Charadrius dubius curonicus Hand-list Japanese Birds, rev., 1932, p. 194 (Yap); Hand-list Japanese Birds, 3d ed., 1942, p. 217 (Yap); Mayr, Birds Southwest Pacific, 1945, p. 37 (Micronesia).

Geographic range.--Breeds in northern Europe and Asia. Winters from Africa east to Malaysia and Melanesia. In Micronesia: Caroline Islands--Yap.

Remarks.--The Ring-necked Plover has been recorded at Yap by the Japanese collectors. Mayr (1945a:37) remarks that the bird is an occasional migrant through Micronesia. Gleise and Genelly (1945:221) observed four "Papuan" Ring-necked Plovers at Eniwetok in 1945. Apparently no specimen was obtained.

Charadrius alexandrinus dealbatus Hand-list Japanese Birds, rev., 1932, p. 194 (Palau); Hand-list Japanese Birds, 3d ed., 1942, p. 217 (Palau); Mayr, Birds Southwest Pacific, 1945, p. 37 (Palau).

Geographic range.--Breeds in Japan and possibly on adjacent parts of the Asiatic mainland. Winters south to Malaya. In Micronesia: Palau Islands--exact locality unknown.

Remarks.--The Kentish Plover is known from a single record obtained by Semper in the Palau Islands. It is tentatively assigned to C. a. nihonensis, which breeds directly north of the Palau Islands on Japan. C. a. dealbatus (Swinhoe) breeds more to the west on the Asiatic mainland and adjacent islands south of Japan. Additional specimens are needed before the subspecific status of migrants to Micronesia can be accurately determined.
