"The golden plover frequents waste ground, grassy plains, and wet 

 paddy-fields, and also the edges of rivers, and is generally met with in 

 flocks of considerable size. It breeds in China, and also it is said in some 

 parts of India, laying four eggs in a hollow lined with a few blades of 

 grass. The eggs are yellowish blotched with blackish sepia." (Oates.) 



The Eastern golden plover is found in the Philippines on migration 

 and is then usually in its gray winter dress but specimens have been 

 taken with numbers of black feathers from the summer plumage.
