Sedentary and locally nomadic in N, migratory and partially sedentary in S. Some S populations leave breeding grounds Mar (perhaps) to May, move N through C Australia (Mainly May-Jun) and winter across N Australia from May to probably Sept. Overshooting and wintering birds also occur on islands in Banda Sea and nearby: Romang (Jul), Barbar Is (Aug-Sept) and Aru Is (Apr-Sept). Return migration through C Australia Aug-Oct. N populations apparently move to well-drained, sparsely grassed hills and ridges during wet season (Nov-Mar) and return lower-lying plains during dry season. Records from New Ireland in Bismarck Sea require further investigation. During migrations, often forms loose flocks of 10-15 birds.   (del Hoyo J, Elliott A, Sargatal J (eds), 1999)
