326 PATAGONIAN EXPEDITIONS I ZOOLOGY 



Feet and legs, slaty black. 



Iris, deep brown. 



Adults in winter are plain buffy brown above, each feather with an in- 

 distinct dusky median streak. The feathers of the rump and median 

 upper tail coverts dusky brown with dull buffy terminal edging. The lower 

 parts are dull white, the sides of the neck and the pectoral area strongly 

 suffused with buffy, obscuring the darker streaking, more apparent in the 

 summer plumage. 



Young birds of the year have the general appearance of adults but the 

 suffusion of the darker regions is marked ; it is caused by the terminal 

 greyish white fringing and margining of the feathers. 



Geographical Range. America in general. More common in the in- 

 terior. Breeding on the Arctic coasts. Migrating chiefly in the interior 

 to South America. Reaching as far south as Chili and Northern Argen- 

 tina, and in the interior to Southern Patagonia (S. Lat. 50); accidental 

 in Damara Land, Southwest Africa. 



The naturalists of the Princeton Expeditions obtained Baird's Sand- 

 piper in the interior of Southern Patagonia near Rio Coy. It does not 

 appear to have been at all common at this point and was not observed 

 or taken elsewhere in the region. The two individuals are cited in detail 

 below. 



While the species has been recorded from Chili and Western South 

 America generally, it does not figure as an element in the Patagonian 

 fauna, and apparently the two birds cited are the only known Patagonian 

 records. 



"On the 3d April I met with a party of five small Tringse in a part of 

 the Sauce where it was wide and shallow with low underbanks. I believe 

 they were of this species, but the only one I knocked over managed to 

 hide itself effectually. The next day I shot a female from a boggy bit 

 higher up the river where I often shot Snipe. She rose silently and had 

 somewhat the appearance of a small Snipe ; the food in the stomach was
