In favourable seasons the Pintail is a resident ;

 Golden Plover, and all birds that live and move in 

 immense bodies, it travels often and far in search 

 of food or water. A season of scarcity will quickly 

 cause them to disappear from the pampas ; and 

 sometimes, after an absence of several months, a 

 day*s rain will end with the familiar sound of their 

 cry and the sight of their long trains winging their
