Not nearly so common as the following species, with 
which it usually consorts.

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-shore at Cape San 
Antonio. 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.

Quite one of the commonest Waders, and observed in all 
parts visited during the summer months ; it frequents both 
the coast and inland waters in enormous flocks.
