46 How to Sex Cage Birds. 



brown with paler borders ; lores, side of head, and under parts pale 

 tawny buff, paler on abdomen, but darker on under tail-coverts ; 

 under wing-coverts and axillaries huffish-white. 



Euler's Finch (Spermophila super ciliaris). 



The female is of a darker olive above than the male ; wings 

 crossed by two ochraceous bars (in the male they are buffish-white) ; 

 margins of the quills redder than in the male; eyelids and lores 

 olive-yellow ; sides of head dull olive ; throat olive-yellow ; chest 

 and sides of body yellowish olivaceous brown; under tail-coverts 

 pale brown washed with yellowish at extremities, which are other- 

 wise whitish. 



Reddish Finch (Spermophila nigro-aurantia). 



Unlike the male, the female is olive-brown, the under parts 

 yellowish-white in the centre, which deepens into ochraceous on the 

 under tail-coverts; the flights and tail-feathers are brown edged 

 with olive. 



Plumbeous Finch (Spermophila plumbea). 



Burmeister did not know the female, and Dr Sharpe only notes 

 that a female from Guiana is a much redder bird. Judging from 

 analogy, Burmeister says it is probably of a greyish-olive colour, 

 inclining more to yellowish on the abdomen ; but Mr F. C. Thorpe 

 writes me that it is "uniform light brown; paler, almost whitish, 

 on the vent." 



Guttural Finch (Spermophila gutturalis). 



The female is dull brownish-olive instead of bright olive-green ; 

 below it is paler and more yellow excepting on the breast, which is 

 slightly ruddy ; the wing and tail-feathers are blackish with pale 

 edges ; the beak is horn-grey instead of silver-grey, and the feet 

 more flesh-coloured than in the male. 



Half-White Finch (Spermophila hypoleuca). 



The female is olive-brownish instead of slate-grey as in the male; 

 the wing and tail-feathers darker brown edged with olive-grey; 

 under parts paler and more yellow in tint, the middle of the 

 abdomen and under tail-coverts white; the beak reddish-yellowish- 

 grey; feet pale greyish flesh-coloured. 



The Spectacled Finch and the Black-banded Finch, which have 

 appeared at the London Zoological Gardens, come from Ecuador 

 and Mexico, and therefore are not likely to be frequently offered for 

 sale in the living bird market.
