Young. 



The Black Stilt is a resident of New Zealand ; its alleged occurrence in Australia 

 appears to rest on insufficient evidence. 



The approach of its winter plumage towards the adult dress of the Australian Stilt 

 proves the close relationship of the two species ; and the fact that the young in first plumage 

 have the swollen joint between the tibia and the tarsus, so conspicuous in the young of 

 (Edicnemus, points to its affinity with the birds of that genus. 



Young in first plumage only differ from the same dress of II leucocephalus in having 

 dark brown axillaries, and dark outer webs to the tail-feathers. 



Potts remarks that in the South Island of New Zealand this bird breeds on the sandy 

 river-beds.
