 ashy brown or gray on the breast and sides.

This species may be distinguished from the Black-bellied Plover 

 in any plumage by its gray axillars and the absence of the rudimentary 

 hind toe. 



The Golden Plover was at one time abundant and is still more or 

 less common in Illinois and Wisconsin during the migrations. Arrives 

 from the south the latter part of April and from the north in 

 September. As is the case with others of its family, its numbers are 

 decreasing year by year.
