Corn-Bunting [Emberiza c. calandra). 



Adults. — Complete moult in September and October. No 

 moult in spring, and abrasion has little effect except that the 

 upper-parts become paler and more greyish and the under- 

 parts white. Sexes alike. 



Juvenile. — Much like the adults, but the buff or huffish 

 ground-colour of the upper-parts paler and the black-brown 

 streaks broader and more prominent ; the chin and tluroat 

 are more uniform than in the adult and the wing- and tail- 

 feathers and wing-coverts have well-marked margins and 

 tips of buff. 



First winter. — The juvenile plumage is completely 

 moulted in the first autumn. The birds then become like 

 the adults. 



Yellow Bunting {Emberiza c. citrinella). 



Adults. — Complete moult from August to October, No 

 moult in spring, but abrasion has a considerable effect 

 especially in the male, Avhose crown and throat gradually 

 become more uniform and paler yellow, the uj^per-parts 

 more strongly streaked and the sides of the breast and flanks 

 brighter chestnut. In the female the crown and throat both 

 in winter and summer have much less yellow and more dark 

 green than in the male, the flanks and breast are not so 

 chestnut and the belly is paler yellow. 



Juvenile. — Somewhat like adult female but with no pure 

 yellow on the crown and nape, which are yellowish-brown 

 to pale buff or yellowish-buff streaked black-brown, rump 

 browner and more streaked, under-parts much paler and 

 duller yellow (sometimes greyish only tinged yellow) and the 

 throat, breast and flanks with narrow blackish-brown streaks. 

 The juvenile female appears to be not so yellowish on the 

 crown and paler on the under-parts than the juvenile male. 

 Some specimens do not bear out these distinctions, which
