yery common in the spring and autumn. Common at 
Baradero in April. Always seen in flocks. j 
/ 46. Bhyacophilus solitarius (Wils.) ; Nomencl. p. 146. 
A spring and summer visitor; but I have never found its 
nest, although I have observed it from October to March. 
During this time I have constantly observed it about little 
pools and swamps between Palermo and Belgrano, and also j 
about Campana, on the Parana. It differs from the other - 
Sandpipers here {Gambetta melanoleuca and G. flavipes) in 
preferring the neighbourhood of trees and scrub to the open 
lagunas or arroyos in the campo. In size slightly less j 
than the last-named bird, I have seen no other Sandpiper here 
it can be confounded with. It has a loud sharp note, which 
it utters both on the ground and on the wing, and which is 
very like that of the Green Sandpiper at home. Its food 
consists of soft-bodied aquatic larvse. Iris wood-brown; | 
beak black, with the basal half of both mandibles inclining to | 
orange ; legs and feet between pea- and olive-green. |
