These specimens are in moult and have almost assumed the 

 adult winter dress, but have not yet lost the wing-coverts 

 of the young plumage. 



Two or three parties of Knots, comprising eight or ten 

 individuals, were observed on the sea-sliore at Cape Saa 

 Autonio. This appears to be a new record for Argentina, 

 but is not unexpected, perhaps, as the bird has been traced 

 as far south as Brazil.

 parts visited during the summer months ; it frequents both 

 the coast and inland waters in enormous flocks.
