The Black-winged Stilt genus (Himantopus sp.) has a worldwide distribution with populations occurring on all continents expect Antarctica (del Hoyo et al., 1996). Some populations are sedentary; others are migratory (or at least partially so). In Australia the local species, recently reclassified as White-headed Stilt Himantopus leucocephalus, is regarded as resident (Higgins & Davies, 1993).
