increasing towards the tip where they are as numerous as on the back 

 and a little coarser. Four broad bars of grey, the two apical bars 

 darker, and becoming quite black on the two central feathers, 

 similar in character to the black vermiculated bars on the back ; all 

 the rectrices, with the exception of the two central ones, tipped 

 white. 



The feathers on the nape are curiously downy and those in the 

 centre are often without any vermiculations. Sides of the head 

 whitish buff with black striae ; chin and throat buffy white ; fore neck 

 pale buflf, finely vermiculated with black ; on the upper breast the 

 buJS" changes to a beautiful french grey and the vermiculations almost 

 disappear ; lower tail coverts buffy white, much splashed and marked 

 with brown, this colour forming into well marked bars on the outer 

 webs of the outermost feathers ; remainder of lower parts white. 

 Primaries black, the bases white and the outer webs buff, this colour 

 being most pronounced on the first primary, the inner webs white 

 for two-thirds of their length, outer secondaries the same but with 

 no buff on the outer webs and with the tips white ; inner second- 

 aries like the scapulars ; lesser wing coverts like the back , median 

 coverts the same but albescent ; greater coverts with broad, black 

 sub-terminal bars and white tips ; winglet black. 



Both males and females have a ruff of feathers starting from the 

 sides of the neck and, to some extent, from the hind neck, the 

 latter are sparse and thin, mixed black and white but with the 

 former predominating ; the feathers at the sides form two long tufts, 

 the inner are white on the basal halves and black on the terminal 

 halves which are much broader ; outside these the feathers are 

 ' white, of the same breadth throughout and generally longer than 

 the broader black feathers, here and there may be seen a few faint 

 bars of grey or specks of black. The feathers of the sides of the 

 breast are very full and long forming a continuation of the ruff. 



The feathers of the crest may measure as much as 3-2" in length 

 whilst the longer feathers of the ruff are sometimes well over 7" and 

 those of the breast up to, or even over, 3". 



In old birds the grey on the breast appears to become purer and 

 more extensive whilst the vermiculations become fewer and fewer. 



" The irides vary from pale to bright yellow.
