Description : adult male. — Williams' Silver Pheasant is a sub-species 

 intermediate between cuvieri on the North and West and rufipes 

 on the East, and is an evolution on somewhat parallel lines with 

 that of oatesi which comes between cuvieri and lineatus in the South 

 and West. In the present sub-species, however, the black and white 

 markings of the upper plumage are distinct bars and lines rather than 

 vermiculations, though both bars and lines may be very fine. The 

 general aspect of the upper plumage is a grey, the black and white 

 markings being about equal in extent. The rump and upper tail 

 coverts contrast quite strongly with the rest of the upper plumage, 

 the feathers here being broadly fringed with white, preceded by one 

 broad and one less broad band of white, the rest of the bars of the 

 feather being vermiculated. Occasionally fine bars instead of broken 

 vermiculations extend to the base of the feather. The variations 

 are not due to age, as birds still retaining feathers of the first 

 plumage have these parts finely vermiculated practically throughout, 

 whilst others have them equally barred. The crest is black. The 

 under parts are black, showing broad white lines or striae on the 

 sides of the breast and flanks in varying degree. 



The female cannot be invariably distinguished from that of 

 horsfieldi, but is on an average paler and more rufous, more especially 

 on the rectrices.
