Coastal birds supposedly resident, but subject to extensive local disperesals; in very dry season in Surinam, moves inland following rivers. Now only non-breeding visitor to Trinidad. Migrates from parts of ilanos in Venezuela during dry season, possibly N to coast; flocks fly at great heights, usually in V-formation. Flies long distances, sometimes several kilometres, from nesting or roosting site to foraging areas. Vagrant to West Indies; sightings in SE USA might involve only escapes, though some have occurred after tropical storms.   (del Hoyo J, Elliott A, Sargatal J (eds), 1992)
