WHITE-RUMPED SWIFT. 
The species is given in the Catalogue of the Birds in the British Museum^ 
Vol. XVI., p. 448, 1891, as having as habitat, “ Mongolia, Baikal and the 
Amoor in the north, Assam, Cachar and Burmah in the west, and extending 
over China and Japan to Austraha, where it is probably only a winter visitor.’* 
The exact breeding place of the Australian visitor is at present unknown 
as the above range is now known to cover subspecific forms and, as noted 
above, the breeding plumages are not exactly determined.
