Speculated to undertake migrations between N & S South America, but unlikely in view of occurrence in Apr- Aug in Brazil (Taubatè) and Apr-Jun in Uruguay, and enlarged gonads of an Aug Venezuela specimen. One from Colombia (Mar 1959), and 3 from ships at sea have led to suggestions that birds occasionally erupt large distances randomly from centres of distribution in tropical savannas and range may be wider and more continuous than currently known. Twice taken on ships at sea, the holotype being collected to the Beagle in 1831 at mouth of R de la Plata, while one flew abroad ship off Cabo Santa Marìa, Uruguay, in Nov or Dec 1875, such records probably indicative at least of post-breeding dispersal. Also possible record from Falkland Is, Apr 1921, probably a straggler.   (del Hoyo J, Elliott A, Sargatal J (eds), 1996)
