2o8 BIRDS OF LA PLATA

 Entrerios on 9th September^ 1880, " in large flocks," 

 After the middle of October not one was seen. 



The same excellent observer saw it almost daily

 company with the Golden Plover and Bartram's 

 Sandpiper, until late in February." 



From the 8th to the loth of October, 1877, Dum- 

 ford saw large flocks of this Whimbrel in the Chupat 

 valley flying south, and obtained two specimens. 

 Capt. Packe and Capt. Abbott both procured examples 

 in the Falkland Islands.

 its season on the pampas in my day, appearing in 

 September to October in small flocks of thirty or 

 forty to a hundred or more, and often associating 

 with the Golden Plover ; but, as I now hear from 

 the authorities of the Smithsonian Institution at 

 Washington, it is practically extinct.-
