AVES CHARADRIID^ 307 



"Female. La Plata, Buenos Aires, Arg. Rep., Nov. lo, 1882. 



" Iris dark sepia. 



"Frequents the lagoons in flocks of about thirty." (E. W. White, P. 

 Z. S. 1883, p. 42.) 



The adult female in the hyeeding plumage is similar to the male, but less 

 deeply colored and never apparently assuming the reddish plumage so 

 fully. 



Adults in zvinter plumage. — Upper parts ashy brown with dusky shaft 

 lines to the feathers, becoming darker on the lower back and rump. 

 Upper tail coverts white with black tips. Tail black, white at base. The 

 quills much as in summer except that the innermost secondaries are brown 

 like the back. The crown of the head is ashy brown. Lores and 

 feathers in front of the eyes deeper brown, and above this a streak of dull 

 white. Face and cheeks ashy grey, paler below the eye. Upper neck 

 ashy brown with a fulvescent shade, sides of neck ashy grey, extending 

 over the lower throat, fore-neck and chest, the remainder of the under- 

 body, upper throat and chin being white. Axillaries and under wing 

 coverts much as in the summer plumage. 



Young birds of the year are similar in general appearance to the adults 

 in winter plumage. They are a little darker in general tone. The 

 feathers of the upper parts are mottled, the edge of each feather being 

 tawny buff, and having a sub-terminal black and buffy barring. The 

 inner secondaries and the central tail feathers are barred or mottled in a 

 similar manner. The general tone of the lower parts is more buffy than in 

 adults in winter ; sides of body browner and the axillaries and under- 

 wing coverts much as in adults. 



Geographical Range. — North America, from Alaska to Hudson Bay 

 and north in the breeding season. Migrating southward east of the Rocky 

 Mountains and through the eastern United States by way of the greater 

 Antilles to South America, where it has been found in winter as far south 

 as Chili, Patagonia, the Straits of Magellan and the Falkland Islands. 



The Hudsonian Godwit was not observed by the naturalists of the 

 Princeton Expeditions. The material for the descriptions given above is 

 in the British Museum of Natural History and in the Princeton University
