Wing-end of Tcsnioptera murina. 



Tcenioptera is a characteristic form of the American Pampas, but 

 extends as far north as the Amazons and into Chili and Bolivia, 

 where, however, it probably only occurs in the more open districts. 

 The plumage is mostly white and black, with slight rufous markings 

 in some species. The bill is somewhat constricted, the legs long and 

 strong. The tail is usually lengthened, and square at the end or 

 slightly forked. A curious acumination of the outer primaries 

 occurs in the males of several species.
