264 A PRACTICAL HANDBOOK OF BRITISH BIRDS. 



green (forming green speculum) sometimes with magenta-coppery 

 gloss, inner webs mostly white and in some with white tips, inner- 

 most secondaries with outer webs cinnamon -rufous, paler towards 

 tip, and inner webs more or less grey or white, some short innermost 

 slate -grey ; bastard- wing black ; median and lesser primary- 

 coverts black or grey-black, vermiculated light buff or white ; 

 greater, median and lesser coverts white or white washed pink-buff. 

 This plumage is acquired by partial moult Dec. to April involving 

 most body -feathers, central pair of tail-feathers, innermost second- 

 aries and coverts. N.B. — Cinnamon -rufous of upper- and under- 

 pays is very variable in shade and becomes much faded in worn 

 plumage. 



Adult male. Eclipse. — No material with remiges in quill 

 examined. One (<£ ad. 19/7/99 Brit. Mus.) is moulting some feathers 

 of upper and under-parts, rest of body-plumage and wings worn. 

 One (Sept., Tibet, no sex but apparently <$) has wings, tail and much 

 body -plumage new, no black collar. Two (Nov.) also want black 

 collar. Only difference I can find between eclipse and winter- 

 summer is absence of black collar* in eclipse. This plumage is 

 apparently acquired by a more or less complete moult from July 

 onwards. 



Adult female. Winter and summer. — Coloration as male, but 

 without black ring round neck and fore-head to crown, lores, area 

 round eye, streak behind eye and usually chin white. Moult as in 

 male. Eclipse. — No specimens moulting remiges examined. Appar- 

 ently moult as in male and no difference in coloration between 

 eclipse and winter-summer. 



Nestling. — Similar to T. tadorna but does not appear to have 

 small patch of white in centre of brown patch on mantle. 



Juvenile. Female. — (No male examined.) — Fore-head light 

 buff ; crown pale drab-grey, feathers edged buff ; nape cream-buff 

 or warm buff, feathers with pale drab-grey bases ; upper-mantle 

 as adult ; scapulars hair -brown with cinnamon -buff or buff fringes,, 

 which in some are more or less vermiculated hair-brown and cinna- 

 mon-buff, some of upper ones cinnamon-rufous, lower scapulars 

 dark hair-brown faintly edged cinnamon-rufous ; back and rump 

 as adult but rump not such an intense black and only faintly 

 glossed green ; upper tail-coverts black-brown tipped warm buff ; 

 cheeks, sides of neck, chin, throat and fore-neck cream-buff or warm 

 buff ; under-parts pink- chestnut, in some pink-buff, deeper on 

 belly and vent, flank-feathers with hair -brown bases ; tail as adult 

 but narrowly tipped buff ; wing as adult but innermost secondaries 

 with inner webs hair -brown, outer webs more or less cinnamon - 

 rufous ; greater coverts white clouded mouse -grey, paler on outer 

 webs, which are sometimes white, innermost tipped buff ; median 

 coverts white usually suffused towards tip with pale mouse -grey 



* One Nov. $ has some new feathers marked blackish forming an in- 

 definite collar.
