The golden plover was one of the most abundant migrants to pass 

 through Micronesia during 1945. Birds were found on beaches, 

 cleared areas, air strips, and short-grass uplands. At Guam, north- 

 bound birds were first seen on February ii. By April i, plover in 

 nuptial plumage were numerous. The last spring record was ob- 

 tained on April 28. The first southbound birds were recorded on 

 July 8, when three individuals were seen at Agfayan Bay. By Sep- 

 tember, plovers were again numerous. Birds in postnuptial molt 

 were taken at Ulithi in August, at Palau in September, and at Guam 

 as late as October 8. The five birds taken at Rota in late October were 

 in winter plumage. McElroy saw birds at Truk in December. 



Weights of seven males from Guam and Rota are 107-125 (117), 

 of four females 109-120 (114). Stomach contents of birds examined 

 at Ulithi and Peleliu included small shells and parts of crabs.
